Nothing will sober you up faster than time. Your liver clears alcohol at a fixed rate of about .015 to .020 BAC per hour, which means someone at the legal limit of .08 still needs four to five hours to reach zero. But while you wait, several things genuinely help you feel better, stay safe, and avoid a worse morning.
Water and Salty Snacks First
Alcohol suppresses the hormone that tells your kidneys to hold onto water, so you lose fluid fast. Along with that fluid, you lose key minerals: potassium, magnesium, calcium, and sodium. That mineral loss is a major reason you feel shaky, weak, or nauseous. Drinking water between alcoholic drinks or once you’ve stopped slows dehydration, and sipping a sports drink or coconut water helps replace those lost electrolytes more effectively than water alone.
Don’t chug a huge amount of water at once if your stomach is already upset. Slow, steady sips are easier to keep down. A handful of salted crackers or pretzels gives your body some sodium and a small hit of carbohydrates, which matters more than you might think.
Eat Something Substantial
Alcohol blocks your liver’s ability to release stored sugar into your bloodstream. When blood sugar drops, you get dizzy, foggy, shaky, and sometimes irritable. Eating food that combines carbohydrates, protein, and a little fat helps stabilize those levels. Toast with peanut butter, a banana, eggs, or even a bowl of cereal with milk all work well. The carbs give your body quick fuel, the protein and fat slow digestion and keep that fuel coming steadily.
If you haven’t eaten yet, food also slows the absorption of any alcohol still in your stomach. The earlier you eat, the more it helps. But even after you’ve stopped drinking, a meal supports your body through the hours of processing ahead.
What Doesn’t Actually Work
Coffee, cold showers, and energy drinks are the classic “sober up” tricks, and none of them change your BAC at all. The CDC is clear on this: caffeine does not reduce the effects of alcohol on your body. It can make you feel more alert, which tricks you into thinking you’re less impaired. That false confidence is actually dangerous if it leads you to drive or make decisions you wouldn’t otherwise make.
Cold showers work the same way. They shock you awake, but your liver processes alcohol on a fixed schedule regardless of water temperature. The Hazelden Betty Ford Foundation puts it simply: one standard drink takes about one hour to clear, and nothing speeds that up.
Supplements marketed as hangover cures deserve skepticism too. Dihydromyricetin (DHM), a popular ingredient in “anti-hangover” pills, showed no meaningful effect on alcohol metabolism in clinical testing. It did not lower blood alcohol levels or reduce the toxic byproduct (acetaldehyde) that causes much of the damage. Save your money.
Avoid Certain Pain Relievers
If you have a headache while drinking or afterward, reach for ibuprofen rather than acetaminophen (Tylenol). Your liver uses the same enzyme pathways to process both alcohol and acetaminophen, and combining the two increases the production of a toxic byproduct that can damage liver cells. While the risk is highest with large doses or chronic heavy drinking, it’s an easy one to avoid entirely. Ibuprofen is gentler on your liver in this situation, though it can irritate your stomach, so take it with food.
Sleep on Your Side
If you or someone you’re with is very drunk and ready to sleep, lying on one side (not the back) is one of the most important things you can do. Alcohol suppresses the gag reflex, so a person who vomits while lying on their back can choke without waking up. The recovery position keeps the airway clear:
- Extend the lower arm out at a right angle from the body, palm facing up.
- Fold the upper arm so the back of that hand rests against the cheek closest to the ground.
- Bend the top knee at a right angle to keep the body from rolling flat.
- Tilt the head back slightly and lift the chin to open the airway.
Check on the person periodically. Don’t leave someone who is heavily intoxicated alone to sleep it off.
Signs That Need Emergency Help
Most of the time, being drunk is uncomfortable but not dangerous. Alcohol poisoning is the exception, and it can be fatal. Call emergency services if you notice any of these in yourself or someone else:
- Slow breathing: fewer than 8 breaths per minute
- Irregular breathing: gaps of 10 seconds or more between breaths
- Bluish or very pale skin, especially around the lips and fingertips
- Extremely low body temperature (skin feels cold and clammy)
- Unconsciousness where the person cannot be woken up
- Seizures
Alcohol poisoning happens because BAC can keep rising even after someone stops drinking, especially if they consumed a large amount quickly. The alcohol sitting in the stomach continues to absorb. A person who seems “just really drunk” can get significantly worse over the next hour.
A Realistic Timeline
If you had four or five drinks over a couple of hours, you’re looking at roughly three to five hours before your body fully clears the alcohol. During that time, the most helpful things you can do are straightforward: drink water steadily, eat something with carbs and protein, rest on your side, and let time do its job. You’ll feel the improvement gradually, not all at once. The nausea and dizziness typically ease before the mental fog does, so give yourself more time than you think you need before doing anything that requires sharp judgment.
