There is no way to speed up how fast your body processes alcohol. Your liver breaks down roughly one standard drink per hour, and nothing you do will change that rate. Your blood alcohol concentration drops by about .015 to .020 per hour, and the only thing that truly sobers you up is time.
That said, there are things you can do to feel better, stay safer, and avoid making yourself worse while you wait.
Why Nothing Can Speed Up Sobriety
Your liver handles nearly all the alcohol you drink, and it works at a fixed pace. Think of it like a bottleneck: no matter how much alcohol is waiting in line, your liver can only process about one drink’s worth every 60 minutes. A “standard drink” in the U.S. contains about 14 grams of pure alcohol, which equals roughly a 12-ounce beer, a 5-ounce glass of wine, or a 1.5-ounce shot of liquor.
So if you’ve had five drinks, you’re looking at approximately five hours before your body clears the alcohol. There’s no shortcut. No supplement, no trick, no household remedy changes the speed of that enzyme system in your liver.
Coffee, Cold Showers, and Other Myths
The idea that coffee sobers you up is one of the most persistent myths about alcohol. Caffeine does not lower your blood alcohol level at all. The FDA has reviewed this directly: caffeine does not affect alcohol metabolism, does not improve motor coordination, and does not speed up your visual reaction time while intoxicated. What it does do is make you feel more alert, which is arguably worse. You end up with a person who feels capable of driving or making decisions but whose brain and reflexes are still impaired. The FDA specifically warns that mixing caffeine with alcohol is dangerous because it masks the feeling of being drunk without reducing actual intoxication.
Cold showers fall into the same category. The Virginia Department of Forensic Science states it plainly: only the passage of time will sober someone up. A cold shower might shock you into feeling more awake for a few minutes, but your BAC stays exactly the same. Exercise doesn’t work either. While your body does eliminate a tiny fraction of alcohol through sweat and breathing, it’s negligible compared to what your liver handles.
What Actually Helps While You Wait
You can’t speed up the clock, but you can make the waiting period safer and more comfortable.
Eat something. This is the single most useful thing you can do. Eating food while you still have alcohol in your system increases the rate your body clears alcohol from your bloodstream by 25 to 45 percent, according to Johns Hopkins University. Food slows absorption in the stomach and supports the metabolic processes your liver relies on. A meal with protein, fat, and carbohydrates is ideal. Even a late-night snack helps.
Drink water. Water will not sober you up, but alcohol is a diuretic, meaning it makes you urinate more and lose fluids. Dehydration is responsible for many of the worst symptoms people associate with being drunk and hungover: headaches, dizziness, nausea, and fatigue. Drinking water between alcoholic drinks or while you’re waiting to sober up helps your body recover from that fluid loss. It also slows you down if you’re still drinking, giving your liver more time to keep up.
Stop drinking. This sounds obvious, but your liver can only clear about one drink per hour. Every additional drink you have resets and extends the timeline. If you want to sober up, the first step is to stop adding to the line.
Rest. Sleep doesn’t accelerate alcohol metabolism, but it gives your body time to work without you making impaired decisions. If you’re in a safe place, lying down and sleeping it off is one of the better options available to you.
Avoid Painkillers While Still Intoxicated
If you’re tempted to take something for a headache while you’re still drunk, be very careful with acetaminophen (Tylenol). Your liver uses the same protective molecule to process both alcohol and acetaminophen. When you’re drinking, your liver’s supply of that molecule gets depleted, and adding acetaminophen on top can overwhelm it. The combination raises your risk of liver damage, and in severe cases, liver failure. Acetaminophen toxicity accounts for nearly half of acute liver failure cases in North America.
If you drink regularly or heavily, keep your acetaminophen use rare and stay under 2,000 mg in a day. If you have any history of liver disease, avoid the combination entirely. For occasional mild pain, ibuprofen is generally a safer choice while alcohol is in your system, though it carries its own risks for stomach irritation.
How to Estimate When You’ll Be Sober
A rough estimate: count your drinks, then count the hours since your first one. Your liver clears about one drink per hour. If you had four drinks over two hours and stopped, you still have roughly two hours of processing left. If your BAC was around .08 (the legal limit for driving in most states), it will take approximately four to five hours to reach zero.
Keep in mind that several factors shift this timeline. Body weight, biological sex, liver health, and whether you ate all play a role. Women generally metabolize alcohol more slowly than men at the same body weight. People with liver damage process it slower still. And these are averages. Your actual clearance rate could be faster or slower on any given night.
The safest approach is to be conservative. If you’re unsure whether you’re sober enough to drive, you probably aren’t. Wait longer than you think you need to.
Signs of Alcohol Poisoning
If someone around you is past the point of “too drunk” and into dangerous territory, knowing the warning signs matters. Alcohol poisoning is a medical emergency, and people die from it every year. The critical signs include:
- Mental confusion or stupor
- Inability to stay conscious or being impossible to wake up
- Vomiting (especially while unconscious)
- Seizures
- Slow breathing, fewer than 8 breaths per minute
- Irregular breathing with gaps of 10 seconds or more between breaths
- Clammy skin, bluish skin color, or extreme paleness
- Very low body temperature
You do not need to see all of these symptoms before calling 911. A person who has passed out from alcohol can die from choking on vomit, from breathing failure, or from dangerously low body temperature. If someone is unconscious and you can’t wake them, that alone is reason to call for help immediately.
