How Long Does It Take to Sober Up

What Does “Sober” Actually Mean?

Being sober doesn’t just mean “feeling better.” It means there’s no longer enough alcohol in your system to impair your thinking, coordination, or reaction time. Depending on how much you drank, that can take hours—even if you feel okay before that.

How Alcohol Is Processed in the Body

Your body processes alcohol through the liver. On average, the liver breaks down one standard drink per hour. A “standard drink” is:

• 12 oz beer (5% alcohol)
• 5 oz wine (12% alcohol)
• 1.5 oz liquor (40% alcohol)

There’s no shortcut to this process. Once you drink, your body needs time to break it down.

How Long Does It Take to Sober Up After Drinking?

In general, it takes about one hour per drink to sober up. So:

• 1 drink = 1 hour
• 2 drinks = 2 hours
• 5 drinks = 5 hours

But if you drink quickly or on an empty stomach, you’ll feel the effects faster—and they’ll last longer.

Factors That Affect How Fast You Sober Up

Not everyone sobers up at the same speed. Here are things that can make a difference:

• Body weight and size
• How fast you drank
• Whether you ate before or during drinking
• Your gender
• Metabolism and liver health
• How much sleep you’ve had

A larger person with food in their stomach may process alcohol faster than a smaller person who skipped meals.

Average Time to Sober Up by Drink Type

Type of DrinkTime to Sober Up

1 beer (12 oz) About 1 hour

1 glass of wine About 1 hour

1 shot of liquor About 1 hour

3 cocktails About 3 hours

5 beers 5 to 6 hours

1 bottle of wine 6 to 8 hours

The clock starts after your last drink. Drinking slowly over several hours gives your body more time to catch up.

Does Coffee or Cold Showers Help?

No. These tricks may make you feel more awake, but they don’t lower your blood alcohol level.

• Coffee: Can mask how impaired you are.
• Cold shower: It may make you alert, but your liver still works at the same pace.
• Exercise or sweating: Has little effect on alcohol removal.

Only time sobers you up.

Breathalyzers and Sobriety: What They Show

A breathalyzer measures the alcohol in your breath and estimates your Blood Alcohol Concentration (BAC). Most states in the U.S. have a legal limit of 0.08% for drivers.

Even if you feel okay, your BAC could still be high. That’s why it’s risky to guess based on how you feel.

How Long Does It Take to Pass a Breath Test?

Let’s say you drank 5 beers in 2 hours. Your BAC could easily hit 0.10% or higher. It may take 6 to 8 hours to drop below 0.03%, depending on your body and drinking speed.

You should wait at least 12 hours after heavy drinking before you even consider driving.

Myths About Sobering Up Quickly

Let’s clear up some common myths:

• “I can just sleep it off.”
• Sleep doesn’t speed up your liver. You may still wake up impaired.
• “I’ll just throw up the alcohol.”
• Once it’s in your bloodstream, vomiting won’t help.
• “Water will fix it.”
• Water helps with dehydration but doesn’t sober you up faster.

Alcohol Poisoning vs Just Being Drunk

Alcohol poisoning is a medical emergency. It happens when you drink too much too fast. Signs include:

• Vomiting while unconscious
• Cold or bluish skin
• Slow or irregular breathing
• Seizures
• Confusion or unresponsiveness

If someone has these symptoms, call emergency services right away. Don’t let them “sleep it off.”

Can You Speed Up the Process Safely?

The truth is, you can’t. Your liver handles alcohol at its own pace.

What you can do is support your body:

• Stay hydrated
• Rest
• Eat light, healthy food
• Avoid mixing with other substances (like medications or drugs)

But even with these, your BAC drops only about 0.015% per hour.

Tips to Stay Safer While Drinking

If you plan to drink, use these tips to stay safe:

• Eat a solid meal first
• Sip drinks slowly
• Alternate alcohol with water
• Set a drink limit
• Plan a ride home in advance
• Avoid shots or high-alcohol drinks

Safety starts before the first drink.

How Long Should You Wait Before Driving?

Even if you feel fine, wait at least 1 hour per standard drink—and add an extra hour to be safe.

Better yet:

• Use a breathalyzer if you have one
• Get a ride from a sober driver
• Use a rideshare app
• Wait until the next day

Driving buzzed is still dangerous—and often illegal.

Hangover vs Sobriety: What’s the Difference?

You might feel awful, but still be sober. A hangover is the result of:

• Dehydration
• Low blood sugar
• Sleep disruption
• Inflammation

Your BAC can be zero while your body still feels terrible. That doesn’t mean you’re still drunk—but you may still be unfit to drive or work safely.

When to Get Medical Help

Call a doctor or emergency line if someone:

• Loses consciousness after drinking
• Has seizures
• Can’t stay awake
• Breathing is slow or stops
• Has pale, clammy, or blue skin

Don’t wait. It’s better to be safe than sorry.
