There is no way to instantly sober up. Your liver processes alcohol at a fixed rate, roughly one standard drink per hour, and nothing speeds that up. The only thing that truly lowers your blood alcohol level is time. But while you wait, there are real steps you can take to feel better, stay safe, and help your body recover.
Why You Can’t Speed Up Sobriety
Your liver breaks down alcohol at a rate of about 10 to 30 mg/dL per hour, depending on your body size and liver function. That translates to roughly one standard drink every 60 to 90 minutes for most people. This is a biological speed limit. Your liver uses a specific set of enzymes to convert alcohol into less harmful substances, and those enzymes can only work so fast. Drinking four drinks means you’re looking at four or more hours before your blood alcohol level returns to zero.
Coffee, cold showers, fresh air, and exercise will not reduce your blood alcohol level. New York’s Governor’s Traffic Safety Committee puts it bluntly: nothing sobers you up except time. A cold shower might shock you into feeling more alert for a few minutes, but your coordination, reaction time, and judgment remain impaired. Coffee does the same thing: it masks drowsiness without touching the alcohol still circulating in your blood. These tricks can actually make things more dangerous by convincing you that you’re more capable than you are.
What Actually Helps While You Wait
Drink Water
Alcohol suppresses the hormone that tells your kidneys to hold onto water. That’s why you urinate so much more when drinking. The result is dehydration, which makes the dizziness, headache, and nausea you’re feeling significantly worse. Sipping water steadily won’t lower your blood alcohol, but it will ease many of the symptoms that make being drunk miserable. Alternating a glass of water between any remaining drinks also slows your overall intake.
Sports drinks or drinks with electrolytes can help too, since your body loses minerals along with all that extra fluid. If plain water makes you feel more nauseous, try small, frequent sips rather than gulping a full glass.
Eat Something, Especially Carbs
If you haven’t eaten, food can still help even after you’ve been drinking. A meal high in carbohydrates has been shown to reduce peak blood alcohol levels and lower them at the two-hour mark compared to drinking on an empty stomach. Bread, rice, pasta, crackers, or toast are all good options. Interestingly, high-protein meals didn’t have the same measurable effect on blood alcohol in the same research, so carbs are your best bet here.
Food also helps stabilize your blood sugar. Alcohol interferes with your liver’s ability to release stored glucose, which can cause your blood sugar to drop. That drop contributes to shakiness, weakness, and feeling foggy. Eating something starchy addresses this directly.
Rest in a Safe Position
Sleep is one of the most practical things you can do, because it lets time pass while your liver does its work. If you’re very drunk, lie on your side rather than your back. This is important: if you vomit while on your back, you can choke. Lying on your side with a pillow behind you to prevent rolling over is the recovery position, and it can be lifesaving.
Signs That Need Immediate Help
Most of the time, being drunk is uncomfortable but not dangerous. However, alcohol poisoning is a medical emergency and kills people every year. Know the difference between being very drunk and being in danger:
- Slow breathing: fewer than eight breaths per minute
- Irregular breathing: gaps of more than 10 seconds between breaths
- Vomiting while unconscious or inability to be woken up
- Seizures, blue-tinged skin, or extremely low body temperature
- Irregular heartbeat or a heartbeat that seems to stop and start
If you or someone with you shows any of these signs, call emergency services. Do not assume they’ll “sleep it off.” Blood alcohol can continue rising for 30 to 40 minutes after the last drink, meaning someone can go from very drunk to dangerously poisoned even after they’ve stopped drinking.
What About Supplements and “Sober Up” Products?
You may have seen products containing dihydromyricetin (DHM), a compound extracted from a plant sometimes called the Oriental raisin tree, marketed as a way to sober up faster or prevent hangovers. The reality is that as of 2024, there have been no controlled human studies published that have assessed the safety, optimal dosing, or effectiveness of DHM in people. A Phase 1 clinical trial is currently underway just to establish basic safety in healthy volunteers. Animal studies have shown some interesting results, but that’s a long way from a proven remedy you can rely on tonight.
The same goes for most “anti-hangover” pills, patches, and drinks. None have strong clinical evidence showing they speed up alcohol metabolism in humans. Your liver sets the pace, and no commercially available supplement has been proven to change it.
A Realistic Timeline
Here’s a rough guide to how long it takes for alcohol to leave your system based on how much you’ve had:
- 2 drinks: about 2 to 3 hours
- 4 drinks: about 4 to 6 hours
- 6 drinks: about 6 to 9 hours
- 8 or more drinks: 8 to 12+ hours
These are estimates for an average-sized adult. Smaller body size, liver conditions, certain medications, and whether you ate beforehand all shift the timeline. Women generally metabolize alcohol slightly slower than men at the same body weight due to differences in body composition and enzyme levels.
Keep in mind that “not feeling drunk anymore” doesn’t mean the alcohol is gone. You can still be legally impaired and have slowed reflexes well after the spinning and slurred speech have stopped. If you need to drive or do anything requiring sharp judgment, give yourself more time than you think you need.
The Short Version
Drink water. Eat carbs. Lie on your side if you need to sleep. Wait. That’s genuinely the best you can do. Everything else is either a myth or unproven. Your liver is already working as fast as it can.
