The honest answer: time is the only thing that truly sobers you up. Your liver clears alcohol at a fixed rate of about 0.015 BAC per hour, which works out to roughly one standard drink per hour. No shortcut, supplement, or trick can speed that up in any meaningful way. But there are things you can do right now to feel better, stay safe, and recover faster.
Why You Can’t Speed Up Sobering
Your liver does almost all the work of breaking down alcohol. It converts ethanol into a toxic intermediate compound, then into a harmless substance that breaks down into water and carbon dioxide. The enzymes responsible for this process run at a fixed pace. If you’ve had more than your liver can handle in an hour, the extra alcohol just keeps circulating in your bloodstream until the enzymes catch up.
That means if you’ve had five drinks and stopped, you’re looking at roughly five hours before the alcohol is fully out of your system. There is no way to rush this. Your liver simply cannot be pushed harder.
What Actually Helps Right Now
While nothing accelerates your liver’s work dramatically, eating a meal can make a temporary difference. A study published in Annals of Emergency Medicine found that eating a high-calorie meal increased the rate of alcohol clearance by 86% in the two hours after eating. That boost faded back to baseline by four hours, but it’s one of the few interventions with real data behind it. A substantial meal with carbs, protein, and fat is your best bet.
Beyond food, focus on comfort and hydration. Alcohol is a diuretic, meaning it pushes fluid out of your body faster than normal. Drinking water or an electrolyte beverage won’t sober you up, but it will reduce the headache, dry mouth, and fatigue that come with dehydration. Sip steadily rather than chugging large amounts, which can trigger nausea if your stomach is already upset.
Rest matters too. Lying down in a comfortable spot, dimming lights, and letting time pass is genuinely the most effective strategy. Sleep allows your body to keep processing alcohol without you feeling every minute of it.
What Doesn’t Work
Coffee is probably the most popular myth. Caffeine does not lower your blood alcohol level at all. Multiple human studies confirm that combining caffeine with alcohol has zero effect on BAC or on measurable impairments like motor coordination and reaction time. What caffeine does is mask the feeling of being drunk, which is actually dangerous: you feel more alert but your coordination and judgment remain impaired. The FDA has specifically warned that this combination leads people to drink more and take risks they otherwise wouldn’t.
Cold showers, fresh air, and exercise fall into the same category. They might jolt you into feeling more awake for a few minutes, but they do nothing to help your liver work faster. The California Department of Alcoholic Beverage Control puts it bluntly: none of these will help sober a person up.
How to Feel Better the Next Morning
What you drank matters almost as much as how much you drank. Dark liquors like bourbon, whiskey, and red wine contain higher levels of byproducts called congeners, which form during fermentation. Your body has to break these down separately, and the process competes with alcohol metabolism, meaning both the alcohol and its byproducts linger longer. A controlled study found that participants who drank bourbon reported significantly worse hangovers than those who drank the same amount of vodka. Clear, highly distilled spirits tend to produce milder aftereffects.
If the damage is already done, your recovery priorities are simple: water, food, and sleep. Eat something easy on the stomach before bed if you can manage it. Keep water within reach overnight. In the morning, a balanced meal with eggs, toast, or bananas will help restore blood sugar and replenish nutrients your body burned through while processing alcohol.
Staying Safe While Intoxicated
If you’re helping someone who is very drunk, or if you’re trying to sleep it off yourself, body position matters. A heavily intoxicated person who vomits while lying on their back can choke. Always lie on your side with your head turned to the side. Place a pillow behind your back to keep from rolling over. If you’re looking after someone else, check on them regularly. Even though they appear to be sleeping, their blood alcohol can still be rising if they drank heavily right before lying down. Someone who falls asleep drunk can cross into unconsciousness without obvious warning.
Know the line between drunk and in danger. Alcohol overdose is a medical emergency, and the signs are distinct from ordinary intoxication: breathing that slows below eight breaths per minute, gaps of ten seconds or more between breaths, seizures, inability to wake the person, clammy or bluish skin, vomiting while unconscious, or extremely low body temperature. If you see any of these, call 911 immediately. At that point the body’s basic functions are shutting down, and waiting it out is not safe.
A Realistic Timeline
Planning around that one-drink-per-hour rule gives you a practical framework. If your last drink was at midnight and you had six drinks over the evening, your body likely won’t finish processing all the alcohol until around 6 a.m., assuming you stopped at midnight. Your BAC drops by about 0.015 per hour regardless of what you do in the meantime.
This also matters for the morning after. Many people are still technically impaired when they wake up and drive to work. If you drank heavily until 2 a.m., you could still have alcohol in your system at 8 a.m. The only reliable way to know you’re clear is to count backward from your last drink and give yourself at least one hour per standard drink consumed.
