Nothing sobers you up except time. Your liver clears alcohol at a fixed rate of about 0.015 BAC per hour, which means if you’re at the legal limit of 0.08, it takes roughly four to five hours to reach zero. No food, no coffee, no cold shower changes that rate. What you can do is make the wait safer, more comfortable, and less miserable the next morning.
Water and Small Sips of Juice
Alcohol is a diuretic, meaning it pulls water out of your body faster than normal. Drinking water between alcoholic drinks or once you’ve stopped slows dehydration, which is responsible for much of the headache and fatigue you’ll feel later. Sip steadily rather than chugging a huge amount at once, since a stomach full of liquid on top of alcohol can trigger nausea.
Fruit juice has a small additional benefit. Fructose, the sugar naturally found in fruit, has been shown in lab studies to increase the rate of alcohol metabolism by more than 50% in liver cells. That’s a meaningful bump in a petri dish, though the real-world effect in a whole human body is more modest. Still, a glass of orange or apple juice gives you both hydration and fructose, making it one of the better choices you can reach for.
Eat Something Substantial
If you haven’t eaten, food won’t undo what’s already in your bloodstream, but it slows the absorption of any alcohol still sitting in your stomach. The best options combine protein, fat, and carbohydrates. Think along the lines of an egg and cheese sandwich, a bean burrito, or a bowl of rice with some protein. These foods slow the rate at which alcohol moves from your stomach into your small intestine, where most absorption happens. Even a late-night snack can help taper absorption if you’ve been drinking recently.
Why Coffee Doesn’t Work
Caffeine makes you feel more alert, but it does not reduce your blood alcohol level or reverse impairment. The CDC is clear on this point: mixing caffeine with alcohol does not change alcohol’s effects on your body. What it does is mask the sensation of being drunk, which can actually make things worse. You feel more capable than you are, which leads to riskier decisions like driving. Skip the espresso as a sobering tool. If you want something warm, plain water or herbal tea is a better call.
Sleep Helps, but Not as Much as You Think
Lying down and closing your eyes is one of the most useful things you can do while waiting for your body to process alcohol. But the sleep you get while still intoxicated is lower quality than normal. Alcohol delays and shortens REM sleep, the phase most important for feeling mentally rested. This disruption starts at surprisingly low doses. Even two standard drinks reduce REM sleep, and the effect gets progressively worse with more alcohol.
Higher doses (roughly five or more standard drinks) may make you fall asleep faster, but that quicker onset actually worsens the REM disruption later in the night. This is why you can sleep for eight hours after heavy drinking and still wake up feeling foggy and exhausted. You got quantity but not quality.
If you’re going to sleep it off, at least set yourself up well: drink a full glass of water before bed, keep more water on your nightstand, and sleep on your side rather than your back.
The Recovery Position Matters
If someone is very drunk and going to sleep, or if they’ve passed out, placing them on their side is one of the most important things you can do. This is called the recovery position, and it keeps their airway open so that if they vomit, they won’t choke.
To do it: with the person on their back, kneel beside them. Place the arm nearest you out at a right angle, palm facing up. Fold their other arm so the back of their hand rests against the cheek closest to you. Bend their far knee to a right angle, then gently roll them toward you by pulling that bent knee. Their head should rest on their folded hand, and their bent leg keeps them from rolling onto their face. Tilt their head back slightly to keep the airway clear.
Never leave a heavily intoxicated person sleeping on their back unattended.
Signs That Need Emergency Help
Most of the time, being drunk is uncomfortable but not dangerous. There is a line, though, and crossing it means calling emergency services immediately. Watch for these specific warning signs:
- Breathing slows below 8 breaths per minute, or there are gaps of 10 seconds or more between breaths
- Skin turns bluish, very pale, or feels cold, which signals dangerously low body temperature
- The person can’t be woken up or has no response to shouting or shaking
- No gag reflex, meaning they could choke on vomit without any protective cough
- Seizures or continuous vomiting
Alcohol poisoning kills by suppressing the brain’s ability to control basic functions like breathing and temperature regulation. If you see any of these signs, don’t wait to see if they improve. Place the person in the recovery position and call for help.
What the Sobering-Up Timeline Actually Looks Like
Your liver processes alcohol through an enzyme called alcohol dehydrogenase, and it works at a near-constant speed regardless of what you do. The average person drops their BAC by 0.015 to 0.020 per hour. To put that in practical terms:
- 3 drinks (BAC around 0.05–0.06): roughly 3 to 4 hours to clear
- 5 drinks (BAC around 0.08–0.10): roughly 5 to 7 hours
- 8+ drinks (BAC around 0.15+): 10 hours or more
These numbers vary with body weight, sex, food intake, and individual metabolism, but the general pace holds. This is why people who drink heavily on a Saturday night can still be legally impaired on Sunday morning. The only thing that reliably removes alcohol from your blood is the slow, steady work of your liver over time. Sweating in a sauna, taking a cold shower, or exercising won’t meaningfully speed that up. At most, trace amounts leave through breath, sweat, and urine, but the vast majority is processed by your liver alone.
Your best strategy is straightforward: drink water, eat if you can, get on your side, and give your body the hours it needs.
