The only thing that truly sobers you up is time. Your liver processes roughly one standard drink per hour, and nothing you do can meaningfully speed that up. A standard drink is 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of liquor. If you’ve had five drinks, you’re looking at about five hours before your blood alcohol level returns to zero.
That said, there are real things you can do to feel better, stay safe, and support your body while it does the work. There are also popular tricks that flat-out don’t help, and knowing the difference matters.
Why Nothing Speeds Up Your Liver
Your liver breaks down alcohol at a fixed rate of about half an ounce of pure ethanol per hour. That’s a biological constant. It doesn’t change based on how much water you drink, whether you eat a big meal after drinking, or how many cups of coffee you have. Your body produces a specific enzyme to process alcohol, and you only make so much of it at a time. Think of it like a bottleneck: no matter how much liquid you pour in, only so much can pass through per hour.
This rate varies slightly from person to person. Women generally produce less of the enzyme that breaks down alcohol in the stomach, which means more alcohol reaches the bloodstream in the first place. Body size, genetics, liver health, and how often you drink all play a role too. But the differences are modest. No one’s liver works three times faster than average.
What Actually Helps
Stop Drinking
This sounds obvious, but it’s the single most effective decision. Every additional drink resets the clock. If you stop at midnight after four drinks, you’ll likely be near zero by 4 a.m. If you have one more at 1 a.m., you’ve pushed that timeline further out.
Drink Water
Alcohol is a diuretic, meaning it makes your kidneys flush out more fluid than you’re taking in. This is why you urinate so frequently while drinking and wake up feeling terrible. Sipping water between drinks or after you’ve stopped won’t lower your blood alcohol level, but it addresses the dehydration that drives headaches, fatigue, and nausea. Sports drinks or drinks with electrolytes can help even more, since alcohol causes your body to lose magnesium, phosphorus, and other minerals through increased urination.
Eat Something
Food in your stomach slows the absorption of alcohol you’ve already consumed (though it won’t reverse what’s already in your bloodstream). Eating also helps stabilize blood sugar, which drops during heavy drinking and contributes to shakiness, weakness, and feeling foggy. Carbohydrate-rich foods like toast, crackers, or rice are easy on an upset stomach and provide quick energy. If you can manage something more substantial with protein and fat, even better.
Rest or Sleep
Sleep lets time pass and gives your body a chance to recover. There’s a catch, though: alcohol disrupts your sleep quality significantly. It suppresses the deep, restorative stages of sleep and fragments your sleep cycles, so you’re likely to wake up still feeling groggy even after a full night. Still, lying down in a safe environment is far better than trying to push through. If someone is very intoxicated, make sure they sleep on their side, not their back, to reduce the risk of choking if they vomit.
What Doesn’t Work
Coffee
This is one of the most persistent myths. Coffee does not sober you up. The CDC is clear on this: caffeine mixed with alcohol does not reduce alcohol’s effects on your body. It might make you feel more alert and energetic, but your coordination, judgment, and reaction time are still impaired. In some ways, this makes coffee dangerous. You feel more capable than you actually are, which can lead to risky decisions like driving.
Cold Showers
A cold shower will shock you awake, but your blood alcohol level stays exactly the same. You’ll just be cold and wet and still drunk. The temporary jolt of alertness wears off quickly.
Exercise
Working out or going for a run doesn’t burn off alcohol faster. Your liver handles the vast majority of alcohol processing, not your muscles or lungs. Exercising while intoxicated also increases your risk of injury, since your balance and coordination are compromised. You’re also already dehydrated, and sweating makes that worse.
Vomiting on Purpose
Forcing yourself to throw up won’t meaningfully lower your blood alcohol level. Most of the alcohol from a drink is absorbed into your bloodstream within 20 to 30 minutes. By the time you feel drunk enough to consider this, the alcohol is already in your system. Intentional vomiting can also irritate your throat and esophagus and, in someone who is very intoxicated, increases the risk of accidentally inhaling vomit into the lungs.
A Realistic Timeline
Here’s a rough guide to how long it takes your body to clear alcohol, starting from when you stop drinking:
- 3 standard drinks: approximately 3 hours
- 5 standard drinks: approximately 5 hours
- 8 standard drinks: approximately 8 hours
- 10 standard drinks: approximately 10 hours
These are estimates for an average adult. If you finished your last drink at 1 a.m. and you had six drinks over the course of the evening, some of those earlier drinks have already been partially processed. But the last one still needs its full hour. Most people underestimate how long alcohol stays in their system, especially the morning after. If you had eight drinks and stopped at midnight, you could still have alcohol in your blood at 8 a.m.
When It’s an Emergency
There’s a difference between being drunk and experiencing alcohol poisoning. Alcohol poisoning is a medical emergency, and it kills people every year. Call 911 if you see any of these signs in someone who has been drinking heavily:
- Breathing slower than eight breaths per minute, or gaps of more than 10 seconds between breaths
- Skin that looks blue, gray, or unusually pale
- Seizures
- Vomiting while unconscious or semi-conscious
- Inability to stay awake, or being impossible to rouse
- Low body temperature (skin feels cold and clammy)
Do not leave a heavily intoxicated person alone to “sleep it off.” Blood alcohol levels can continue rising after someone stops drinking, because alcohol in the stomach is still being absorbed. Someone who seems okay when they lie down can be in serious trouble 30 minutes later. Roll them onto their side, stay with them, and call for help if anything looks wrong.
Feeling Better the Next Day
Even after your blood alcohol hits zero, you can still feel awful. Hangovers are driven by dehydration, inflammation, poor sleep quality, and the toxic byproducts your liver produces while breaking down alcohol. To recover faster, focus on rehydrating with water or electrolyte drinks, eating easy-to-digest foods, and resting. B vitamins and folic acid are among the nutrients most depleted by alcohol, so a balanced meal goes a long way.
Alcohol also seriously disrupts sleep architecture. Even if you slept for eight hours, much of that sleep was lighter and less restorative than normal. You spent less time in the deep sleep stages your body needs to recover physically. This is why you can sleep a full night after heavy drinking and still wake up exhausted. A short nap later in the day, if possible, can help close that gap.
