There is no way to sober up fast. Your liver processes alcohol at a fixed rate of about one standard drink per hour, and nothing you do can speed that up. If you’ve had five drinks, you’re looking at roughly five hours before your body fully clears the alcohol. That said, there are things you can do to feel better, stay safe, and avoid making the situation worse while you wait.
Why Time Is the Only Real Solution
About 90% of the alcohol you drink is broken down in your liver by enzymes that work at a constant, unchangeable pace. When there’s more alcohol in your blood than your liver can handle, the excess just keeps circulating until the liver catches up. You can’t rush this process any more than you can make your kidneys filter faster by wishing it so.
A standard drink (12 ounces of beer, 5 ounces of wine, or 1.5 ounces of liquor) takes roughly one hour to metabolize. Your blood alcohol concentration drops at a relatively steady rate during that time. So if you stop drinking at midnight after four drinks, you may still have alcohol in your system at 3 or 4 a.m. Planning around this timeline is the most reliable thing you can do.
Common Tricks That Don’t Work
Coffee is probably the most popular “fix” people reach for. Caffeine does make you feel more alert, but the CDC is clear on this: it does not reduce alcohol’s effects on your body. You end up wide awake and still impaired, which can actually be more dangerous than feeling tired, because you may overestimate how sober you are. The same goes for energy drinks or any other caffeinated beverage.
Cold showers, fresh air, and exercise also fail to change your blood alcohol level. They might jolt you into feeling more awake for a few minutes, but your liver is still working at the same pace it was before you stepped into the cold water. The California Department of Alcoholic Beverage Control states this plainly: none of these methods will help sober a person up.
Do Sobering-Up Supplements Work?
A growing market of pills, patches, and IV drips claims to break down alcohol faster or prevent hangovers. The evidence behind them is thin. One widely marketed supplement called Myrkl claims to break down alcohol in the gut before it reaches the liver. A small 2022 study found it had no effect on cognitive function after drinking. It did show slightly less alcohol absorption after a week of daily use, but the study was limited to a small group of participants, and since 90% of alcohol is processed in the liver rather than the gut, the practical benefit is minimal.
In 2020, the FDA issued warnings to multiple companies selling unapproved hangover cure products, including one offering IV therapy and another marketing pills that supposedly metabolize alcohol. There is currently no supplement with strong enough evidence to justify relying on it.
What Actually Helps While You Wait
You can’t speed up sobering, but you can make the wait safer and more comfortable.
Eat something. This is the one area where the science offers a genuine benefit. Research from Johns Hopkins University found that eating food while drinking increases the rate of alcohol elimination from the bloodstream by 25 to 45%. Eating before or during drinking slows alcohol absorption in the first place, which is why drinking on an empty stomach hits so much harder. If you’ve already been drinking, eating won’t erase what’s in your system, but it can help your body clear it somewhat faster.
Drink water. Alcohol is a diuretic, meaning it pulls water out of your body. Dehydration contributes to headaches, nausea, and fatigue. Alternating water between alcoholic drinks, or simply drinking water once you’ve stopped, won’t lower your BAC, but it will reduce how terrible you feel.
Stop drinking. This sounds obvious, but every additional drink resets the clock. If your liver is still processing the last round, adding more alcohol just extends the timeline further.
Rest. Sleep gives your body uninterrupted time to metabolize alcohol. You won’t wake up instantly sober if you’ve had a lot, but you’ll be further along than if you’d stayed up.
Signs That Go Beyond “Too Drunk”
Alcohol poisoning is a medical emergency, and it kills people every year. If someone around you (or you yourself) shows these signs, the situation has moved past waiting it out:
- Slow breathing, fewer than eight breaths per minute
- Gaps of more than 10 seconds between breaths
- Skin that looks blue, gray, or pale
- Seizures
- Vomiting while unconscious or semiconscious
- Inability to stay awake
- Low body temperature
A BAC above 0.31% can cause loss of consciousness, breathing failure, or coma. You don’t need a breathalyzer to act on this. If someone can’t be woken up, is breathing irregularly, or has cold, discolored skin, call emergency services. Do not leave them alone to “sleep it off.” People die from alcohol poisoning because bystanders assumed they were just sleeping.
How to Plan Ahead Next Time
Since you can’t accelerate sobriety, the most effective strategy is managing how much alcohol enters your system in the first place. Eating a full meal before drinking slows absorption significantly. Pacing yourself to one drink per hour keeps your liver roughly in sync with your intake. Tracking your drinks honestly (a strong cocktail can easily count as two or three standard drinks) prevents the surprise of being far more intoxicated than expected.
If you know you’ll need to drive or function at a specific time, count backward. Four drinks means at least four hours before you’re clear, and individual factors like body weight, sex, and liver health can stretch that timeline further. Building in a buffer is always smarter than cutting it close.
