There is no way to sober up fast. Your liver breaks down alcohol at a fixed rate of roughly one standard drink per hour, and nothing you do can speed that up in any meaningful way. If you’ve had five drinks, you’re looking at about five hours before the alcohol fully clears your system. That said, there are things you can do to feel better, stay safer, and avoid making the situation worse while your body does its work.
Why You Can’t Speed Up Alcohol Processing
Your liver handles almost all the alcohol in your body, and it works at its own pace. It processes about half an ounce of pure alcohol per hour, which is the amount in one standard drink (a 12-ounce beer, a 5-ounce glass of wine, or a 1.5-ounce shot of liquor). This rate stays constant no matter what you eat, drink, or do afterward. Think of it like a bottleneck: your liver can only handle so much at once, and the rest stays in your bloodstream until it gets its turn.
This means that if your blood alcohol concentration is 0.08 (the legal driving limit in most states), it will take roughly four to five hours to return to zero. At 0.15, which is common after a night of heavy drinking, you could still be legally impaired the next morning.
Cold Showers, Coffee, and Exercise Don’t Work
These are the most persistent myths about sobering up, and none of them lower your blood alcohol level. A cold shower might jolt you awake, but your BAC stays exactly where it was. Exercise doesn’t help either. Your liver, not your muscles or lungs, eliminates alcohol. Sweating out a hangover might feel productive, but the alcohol in your blood isn’t leaving through your sweat glands in any significant amount.
Coffee is perhaps the most dangerous myth. Caffeine makes you feel more alert, but as the CDC notes, it does not reduce the effects of alcohol on your body. What it creates is sometimes called a “wide-awake drunk,” someone who feels sharper but is just as impaired in coordination, reaction time, and judgment. This false confidence can lead to drinking more or making risky decisions like driving.
What Actually Helps While You Wait
You can’t rush sobriety, but you can make the next several hours more comfortable and reduce the damage alcohol does to your body in the meantime.
Eat Something
Food is the one factor with real evidence behind it. According to Johns Hopkins University, eating while drinking increases the rate of alcohol elimination from the bloodstream by 25 to 45 percent. Food slows the absorption of any alcohol still in your stomach and gives your liver a slightly better working environment. High-protein and high-fat foods are particularly effective because they take longer to digest, keeping the food in your stomach longer. This won’t make you sober in minutes, but it can meaningfully shorten the timeline.
If you’ve already stopped drinking, eating still helps. It stabilizes blood sugar, which alcohol tends to crash, and reduces nausea. Simple, easy-to-digest foods like toast, crackers, bananas, or eggs are good choices.
Drink Water
Alcohol is a diuretic, meaning it makes you urinate more than the volume of liquid you’re taking in. This leads to dehydration, which is responsible for many of the worst symptoms: headache, dizziness, dry mouth, and fatigue. Drinking water won’t lower your BAC, but it addresses dehydration directly. Alternating a glass of water between alcoholic drinks is one of the most effective things you can do during a night out. After you’ve stopped drinking, keep sipping water or an electrolyte drink steadily.
Sleep
Sleep doesn’t metabolize alcohol faster, but it’s the easiest way to let time pass while your body does its job. Alcohol disrupts sleep quality, particularly the deeper, restorative stages, so you may not feel fully rested. Still, lying down in a safe place is far better than trying to push through impairment. If someone is very intoxicated, make sure they sleep on their side rather than their back to reduce the risk of choking.
How Long Sobriety Actually Takes
A rough guide based on standard drinks and average metabolism:
- 2 drinks: about 2 hours to reach 0.00 BAC
- 4 drinks: about 4 to 5 hours
- 6 drinks: about 6 to 7 hours
- 8 drinks: about 8 to 10 hours
These are estimates for an average-sized adult. Body weight, biological sex, liver health, and whether you ate beforehand all shift the numbers. Women generally metabolize alcohol more slowly than men at the same body weight due to differences in body composition and enzyme activity. People with liver damage process alcohol even more slowly.
One important detail: you can still be over the legal limit the morning after heavy drinking. If you had eight drinks and stopped at midnight, your BAC may not reach zero until 8 or 10 a.m. Many DUI arrests happen the morning after, not during the night of drinking.
What to Do Before Your Next Night Out
Since you can’t speed up sobering, the most effective strategy is slowing down how drunk you get in the first place. Eat a full meal before drinking, especially one with protein and fat. Pace yourself to one drink per hour, which matches your liver’s processing rate and keeps your BAC relatively low. Alternate every alcoholic drink with a glass of water.
Plan your transportation before you start drinking. Rideshare apps, a designated driver, or public transit remove the temptation to test whether you “feel fine” behind the wheel. Feeling fine and being sober are not the same thing, especially if caffeine is involved. Your BAC doesn’t care how alert you feel.
