How Long Do the Shakes Last After Quitting Drinking?

Alcohol withdrawal tremors typically begin about six hours after your last drink and, for most people, peak within 24 to 48 hours before gradually fading.¹ That said, the real answer depends heavily on how long and how heavily you were drinking, how many times you have been through withdrawal before, and whether you get medical support. For some people, a mild hand tremor lingers for weeks or even months after the acute phase is over. The timeline is more layered than the simple “a couple of days” answer you might find elsewhere.

The Typical Timeline

The shaking that comes with alcohol withdrawal is one of the earliest symptoms to show up. It usually starts roughly six hours after your blood alcohol level drops significantly, which for daily drinkers often means the morning after a night without drinking or the day after a final binge. Along with the tremor, you might notice sweating, a racing pulse, anxiety, and nausea. These early withdrawal symptoms tend to last between one and two days for most people.¹

The tremor itself is usually worst somewhere between 24 and 72 hours after your last drink. During this window, your hands may shake noticeably when you hold them out in front of you, and fine motor tasks like writing or pouring coffee can feel frustrating. For people with mild to moderate withdrawal, the shaking fades significantly by day three or four, though some residual unsteadiness can hang around for a week or so. For people going through severe withdrawal, the tremor may persist or worsen into more serious symptoms like seizures or delirium tremens, which is why medical supervision matters.

What Causes the Tremor

Your brain adapts to the constant presence of alcohol by adjusting its chemistry. Chronic drinking dampens certain excitatory signals and amplifies inhibitory ones to maintain balance. When you suddenly remove alcohol, that balance collapses. The brain’s excitatory systems, which had been working overtime to overcome alcohol’s sedating effects, are now firing without opposition. This creates a state of nervous system overactivity that produces tremor, rapid heartbeat, sweating, and agitation.²

One specific piece of this puzzle involves norepinephrine, a stress-related chemical messenger. During withdrawal, norepinephrine release surges, and research has shown that the amount released correlates with how severe your symptoms are. People with more norepinephrine flooding their system tend to have worse tremors and greater overall distress.³ This is the same “fight or flight” chemistry that makes your hands shake when you are extremely anxious or scared, but in withdrawal it is amplified far beyond normal levels.

What Alcohol Withdrawal Tremor Actually Looks Like

The tremor of alcohol withdrawal is a postural tremor, meaning it shows up when you hold your hands or arms out against gravity rather than at rest. Electrophysiology studies have found that this tremor runs at about 8 to 12 cycles per second and involves synchronized firing in opposing muscle groups. Interestingly, the pattern is identical to the enhanced physiological tremor you would see in someone under severe emotional stress or anxiety. The only real difference is the amplitude: people in alcohol withdrawal have significantly higher-amplitude shaking than anxious non-drinkers with the same kind of tremor.⁴

In practical terms, this means that alcohol withdrawal tremor is not some unique pathological movement. It is the same tremor everyone’s body is capable of producing under stress, just dialed up much higher. This is why it usually resolves as the nervous system calms down. It also helps explain why people who are anxious about withdrawal sometimes have trouble telling whether they are experiencing genuine withdrawal tremor or anxiety-driven shaking.

Why Some People Shake Longer or Worse Than Others

The single biggest factor that makes withdrawal more severe and longer lasting is having been through it before. This phenomenon, called kindling, means that each round of withdrawal sensitizes the brain so the next one is worse. Research in both animal models and clinical settings has confirmed this pattern: the severity of withdrawal symptoms, including tremor, escalates after repeated episodes.⁵ ⁶ If you have quit and relapsed several times, your withdrawal tremor is likely to be more intense and longer-lasting than someone going through it for the first time.

Other factors that influence how bad the shakes get include:

Drinking pattern: Continuous, daily drinking raises risk more than episodic binge drinking. A continuous pattern of drinking was associated with nearly five times the odds of developing delirium tremens, the most dangerous form of withdrawal.⁷
Amount consumed: Heavier drinkers experience more severe withdrawal. In one study, each additional unit of daily alcohol intake modestly but significantly increased the odds of developing delirium.⁷
Previous delirium tremens: A history of DT is one of the strongest predictors that withdrawal will be severe again. One clinical study found that a previous DT episode roughly quadrupled the odds of it happening again, and when that history was combined with a resting pulse above 100, DT developed in every single case observed.⁸
Cognitive health: Existing cognitive deficits from long-term drinking are associated with worse withdrawal outcomes.⁷

Age, perhaps surprisingly, does not seem to change how long or how severely you experience withdrawal symptoms overall. A study of hospitalized patients across different age groups found no significant differences in the duration or severity of withdrawal between younger and older adults.⁹ That said, there is evidence that the underlying postural tremor associated with alcohol use disorder tends to be more pronounced in men than in women, and that older age is associated with greater tremor intensity generally, even outside the acute withdrawal window.¹⁰

When the Shakes Signal Something Dangerous

For most people, alcohol withdrawal tremor is uncomfortable but not life-threatening. The concern is when tremor is part of a withdrawal that is escalating toward seizures or delirium tremens. DT typically emerges 48 to 72 hours after the last drink, and it involves not just severe tremor but also confusion, hallucinations, dangerously high blood pressure, and fever. Without treatment, DT can be fatal.

Red flags that withdrawal is getting dangerous rather than just unpleasant include a resting heart rate consistently above 100 beats per minute, a fever, disorientation, visual or auditory hallucinations, and seizures. If someone who has stopped drinking develops any of these, they need emergency medical care, not home remedies. The risk is especially high for people with a history of DT or withdrawal seizures, and for those who have gone through multiple previous withdrawals due to the kindling effect described above.⁸

The Shakes That Stick Around After Acute Withdrawal

Here is where the timeline gets murkier and, for many people, more frustrating. Even after the acute withdrawal phase ends, a significant number of people who quit drinking experience ongoing symptoms collectively known as post-acute withdrawal syndrome, or PAWS. This can include anxiety, depressed mood, difficulty sleeping, trouble concentrating, irritability, and yes, tremor. These symptoms tend to develop in early abstinence and can persist for four to six months or even longer.¹¹

The lingering tremor aspect has been specifically studied. In a group of 100 people with alcohol use disorder who had been abstinent for at least 21 days, nearly half still had a detectable postural tremor, compared with only about 3% of non-drinking controls. The good news is that this tremor was never severe, and only about one in six of those affected reported it actually causing problems with daily tasks.¹² So while a subtle shake may be noticeable to you, it is unlikely to be disabling, and it does tend to gradually improve as the brain continues to heal.

This post-acute tremor is thought to reflect the slow rewiring that the brain has to do after chronic alcohol exposure. The neurochemical disruptions that cause acute withdrawal do not fully resolve in a matter of days. The brain’s excitatory and inhibitory systems need time, sometimes months, to find a new equilibrium. For people who drank heavily for years, the healing period is naturally longer.

How Magnesium Plays Into It

One often-overlooked factor in alcohol withdrawal tremor is magnesium. Chronic heavy drinking depletes magnesium from the body, and roughly 30 to 60% of long-term heavy drinkers have low magnesium levels.¹³ Because magnesium normally helps dampen nervous system excitability, low levels can make the hyper-excitable state of withdrawal even worse, contributing to tremor, seizure risk, and muscle twitching.¹⁴

Despite this plausible connection, the evidence for magnesium supplementation as a treatment for alcohol withdrawal is still thin. A Cochrane systematic review found limited evidence on whether giving magnesium actually improves withdrawal symptoms, partly because so few high-quality studies have been conducted.¹⁴ Still, many treatment protocols include magnesium replacement as part of standard supportive care, especially when blood levels are confirmed to be low. It is reasonable to expect that correcting a genuine deficiency would help your nervous system settle down faster, even if the evidence for giving it to everyone in withdrawal is not yet solid.

Medical Treatments That Help

If your tremor is part of moderate to severe withdrawal, medical treatment can shorten how long you feel miserable and dramatically reduce the risk of seizures and DT. Benzodiazepines remain the most established treatment. They work on the same brain receptors that alcohol acts on, essentially substituting a controlled, tapered dose to ease the brain’s transition. Multiple systematic reviews have confirmed them as the treatment with the strongest evidence for managing withdrawal.¹⁵ ¹⁶

For milder cases, or when there are concerns about benzodiazepine dependence, anticonvulsant medications like carbamazepine and gabapentin have shown promise, particularly in outpatient settings for people at lower risk of severe complications.¹⁷ These drugs help quiet the overexcited nervous system through a different pathway than benzodiazepines.

Other medications play supporting roles. Drugs that target the norepinephrine surge, such as clonidine, have been shown in double-blind studies to improve blood pressure, heart rate, and overall withdrawal scores compared to placebo, though they are considered adjuncts rather than standalone treatments.¹⁸ Beta-blockers can help with the physical symptoms of autonomic overactivity, like a pounding heart and visible tremor, but they do not prevent seizures and are not recommended as first-line therapy on their own.¹⁹ ²⁰

Supportive care, which includes vitamin supplementation (particularly thiamine to prevent a serious brain condition called Wernicke’s encephalopathy), hydration, nutrition, and a calm environment, is considered essential alongside any medication.¹⁵ Modern clinical practice favors giving medications based on how severe your symptoms are at regular check-ins rather than on a fixed schedule, which tends to mean less total medication and shorter treatment courses.

How Clinicians Track Your Withdrawal

If you go through medical detox, you will likely encounter a monitoring tool called the CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, revised version). It is a brief scoring system that rates symptoms like nausea, tremor, sweating, anxiety, agitation, and sensory disturbances. The score guides how much medication you receive and when.²¹ A low score means you get less medication or none; a high score triggers more aggressive treatment. This symptom-triggered approach avoids both under-treatment and over-sedation, and it gives a rough answer to “how am I doing?” at each check.

The tremor component of the CIWA-Ar is assessed by having you extend your arms with fingers spread. If there is no visible tremor, that item scores zero. A fine, barely visible tremor gets a low score. A violent, obvious tremor with the arms outstretched gets the highest score. Tracking this over hours and days gives both you and your care team a concrete sense of whether the shaking is improving, stable, or worsening.

When Tremor After Quitting Is Not Withdrawal at All

Not every tremor that appears after you stop drinking is actually caused by withdrawal. Long-term heavy alcohol use can cause lasting damage to the cerebellum, the part of the brain that fine-tunes coordination and movement. This kind of damage can produce a persistent tremor that does not follow the withdrawal timeline and will not resolve on its own as withdrawal symptoms do. It is a consequence of cumulative brain injury rather than an acute withdrawal reaction.

There are also common medical conditions that produce tremor independently of alcohol. Essential tremor, which affects roughly 1 to 5% of adults, is a hereditary condition that causes shaking in the hands and sometimes the head or voice. Hyperthyroidism, caffeine sensitivity, and certain medications can all trigger tremor that might be mistakenly attributed to alcohol withdrawal if the timing happens to line up. If your tremor does not follow the expected withdrawal pattern, gets progressively worse over weeks rather than better, or has features like a head bob or tremor at rest, it is worth getting evaluated separately. The research comparing alcohol withdrawal tremor with anxiety-driven tremor found that the two are physically identical except for amplitude, which means clinical context is the only way to tell them apart.⁴

Putting the Timeline Together

For someone going through alcohol withdrawal for the first time with moderate prior drinking, the shakes usually start within 6 to 12 hours, peak somewhere around 24 to 48 hours, and largely resolve by day 4 or 5. For a heavy long-term drinker with multiple past withdrawals, the acute tremor may be more intense, peak later, and take a full week to calm down, with residual shakiness persisting for weeks. And for nearly half of people with a long drinking history, a subtle postural tremor may be detectable even three weeks or more into abstinence, though it is rarely debilitating.¹²

The broader post-acute withdrawal picture, which includes not just tremor but anxiety, mood changes, sleep trouble, and cravings, can stretch out for four to six months or more.¹¹ That longer timeline is discouraging to hear, but it is worth knowing about, because the most dangerous period for relapse is often when people expect to feel fully recovered but still feel off. Understanding that the brain is still healing months later can reframe those lingering symptoms as progress rather than permanent damage.
