The fastest way to get rid of a hangover is to rehydrate, eat something, take an over-the-counter pain reliever, and sleep it off. There’s no instant cure, but the right combination of steps can cut your misery significantly shorter. Hangover symptoms peak once your blood alcohol level drops back to zero and can last 24 hours or longer, so the goal is to support your body while it clears the toxic byproducts of alcohol.
Why You Feel This Bad
Your liver breaks alcohol down in two stages. First it converts alcohol into a compound called acetaldehyde, which is toxic to your cells. Then a second enzyme clears that compound out. The problem is that after heavy drinking, acetaldehyde builds up faster than your body can eliminate it. That buildup is a major driver of nausea, headache, rapid heartbeat, and the general feeling that you’ve been hit by a truck.
On top of that, alcohol triggers an inflammatory response throughout your body, similar to what happens when you’re fighting off an infection. It also suppresses a hormone that helps your kidneys retain water, which is why you urinate so much while drinking and wake up dehydrated. Dehydration amplifies the headache, fatigue, and dizziness. Some people are genetically worse at clearing acetaldehyde (often the same people who flush red when drinking), and they tend to get hangovers from smaller amounts of alcohol.
Rehydrate Aggressively
Water is the single most important thing you can put in your body right now. Drink a full glass immediately and keep sipping steadily. Plain water works, but adding electrolytes helps more because alcohol depletes sodium, potassium, and magnesium along with fluids. Sports drinks, coconut water, or an oral rehydration solution all do the job. Pedialyte has become a popular choice because it has a higher electrolyte concentration than most sports drinks.
If you’re too nauseated to drink a full glass, take small sips every few minutes. Broth or miso soup is another good option because it delivers both fluid and sodium in a form that’s gentle on an irritated stomach.
Eat Something, Even If You Don’t Want To
Food helps in two ways: it raises your blood sugar (which alcohol tanks) and it gives your body the raw materials it needs to process what’s left in your system. Simple carbohydrates like toast, crackers, or bananas are easy on the stomach and bring blood sugar back up quickly. Bananas are especially useful because they’re rich in potassium, one of the electrolytes you lost overnight.
Eggs are a particularly good hangover food. They’re high in an amino acid that your liver uses to help neutralize acetaldehyde. They also contain other compounds that support liver function during the cleanup process. If you can manage it, a breakfast of eggs, toast, and a piece of fruit covers most of what your body is missing.
Fruit and fruit juice deserve a mention here. Fructose, the sugar found naturally in fruit, appears to speed up alcohol clearance from your bloodstream. One study found that fructose intake increased the rate of blood alcohol metabolism by 67% in men and 92% in women. Eating an orange or drinking some juice isn’t going to instantly sober you up, but it gives your liver a small boost.
Choose the Right Pain Reliever
A standard dose of ibuprofen or aspirin can help with the headache and body aches. Both work by reducing the inflammation that alcohol triggered. However, they can irritate your stomach lining, which is already inflamed from the alcohol, so take them with food and water rather than on an empty stomach.
Avoid acetaminophen (Tylenol) while your body is still processing alcohol. Your liver handles both acetaminophen and alcohol, and combining them puts extra strain on an organ that’s already working overtime. The FDA specifically warns people who drink three or more alcoholic beverages a day to talk to a doctor before using acetaminophen. After a night of heavy drinking, your liver doesn’t need the extra workload.
Sleep More If You Can
Alcohol disrupts your sleep architecture. Even if you were “asleep” for seven or eight hours, you likely spent less time in the deep, restorative stages. Your body does its best repair work during quality sleep, so if your schedule allows it, going back to bed after hydrating and eating is one of the most effective things you can do. Even an extra hour or two of real sleep can noticeably reduce fatigue and brain fog.
What About Coffee?
Coffee doesn’t cure a hangover, but it can help with one specific symptom. If you’re a regular caffeine drinker, skipping your morning cup adds caffeine withdrawal on top of everything else, making your headache worse. A small cup of coffee can relieve that layer of pain. Just be careful: caffeine is a mild diuretic, so it can worsen dehydration if you’re not drinking water alongside it. One cup is fine. A full pot will make things worse.
Supplements That May Help
Red ginseng has some of the more interesting research behind it. In studies, people who took red ginseng extract alongside alcohol reported less fatigue, less thirst, better concentration, and fewer stomach problems than those who received a placebo. Their blood alcohol levels were also measurably lower in the first hour after drinking. The effect appears to come from ginseng speeding up alcohol metabolism, though it also raises acetaldehyde levels temporarily as a result, so the overall benefit is still being studied.
B vitamins and zinc are commonly depleted by alcohol, and some research has found that people with higher intake of these nutrients report less severe hangovers. A B-complex vitamin won’t erase your symptoms, but it may take the edge off, especially if you didn’t eat well before drinking.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol in the morning, is probably the most persistent hangover myth. It does temporarily mask symptoms, but only because you’re raising your blood alcohol level again and delaying the inevitable crash. You’re not treating the hangover. You’re postponing it and adding more toxins for your liver to deal with later. The only situation where more alcohol genuinely stops withdrawal symptoms is in chronic alcohol dependence, which is a completely different medical scenario from a one-night hangover.
Greasy food is another popular recommendation that doesn’t hold up. A heavy, greasy meal before drinking can slow alcohol absorption, which is legitimately helpful. But eating greasy food the morning after does nothing special. Your stomach is already irritated, and heavy food may just make nausea worse. Stick with bland, easy-to-digest options.
A Realistic Timeline
Most hangovers follow a predictable arc. Symptoms are worst in the morning, peak within a few hours of waking, and gradually fade over the course of the day. Mild hangovers often clear up by the afternoon. Severe ones, especially after very heavy drinking, can linger for a full 24 hours or even stretch slightly beyond that.
If you hydrate, eat, take a pain reliever, and rest, you can reasonably expect to feel functional within 6 to 8 hours of waking up. You probably won’t feel 100% until you’ve had a proper night of sleep the following evening. The more aggressively you rehydrate and refuel early in the day, the faster the recovery curve bends in your favor.
