You’re sitting on the couch, the room is spinning just a little bit, and you’re staring at the clock. It was one drink too many. Or maybe it was five. Now, the only thing that matters is the math. You need to know exactly how long can you stay drunk because you have a meeting, a drive, or just a desperate need for the world to stop tilting.
Alcohol is a stubborn guest. It doesn't just leave when you ask it to.
Most people think a cold shower or a greasy burger will do the trick. They won’t. Your liver is a biological machine with a very specific, very unchangeable speed. It doesn't care if you're drinking espresso or Gatorade. It works at its own pace, and until it’s done, you’re still under the influence.
The Cold Hard Math of Your Liver
Let's get the science out of the way first. Your body processes alcohol at a rate of roughly one standard drink per hour.
What's a standard drink? It’s basically 14 grams of pure alcohol. That looks like a 12-ounce beer at 5% ABV, a 5-ounce glass of wine, or a 1.5-ounce shot of distilled spirits. If you knock back three heavy IPAs at 9% ABV in an hour, you haven't just had three drinks. You’ve had closer to six.
Your liver uses an enzyme called alcohol dehydrogenase (ADH) to break things down. This process is linear. Think of it like a narrow hallway; only so many people can squeeze through at once. If you crowd the hallway with ten drinks, the last ones have to wait in line. While they wait, they stay in your bloodstream. That’s why you stay drunk long after the glass is empty.
Why Some People Stay Drunk Longer
It’s not fair, but it’s true: two people can drink the exact same amount and one will be sober while the other is still slurring. Biologically, women often have less ADH in their stomach lining than men, meaning more alcohol hits the bloodstream directly.

Age matters too. As we get older, our water-to-fat ratio shifts. Alcohol is water-soluble. With less water in your system to dilute it, the concentration stays higher. Plus, an older liver is just a tired liver. It’s not as efficient as it was at 21.
Then there’s the food factor. If you drink on an empty stomach, the alcohol hits your small intestine almost immediately. That’s where the majority of absorption happens. If you ate a steak beforehand, the pyloric valve (the gate between your stomach and small intestine) stays closed longer. It buys your liver some time. It won't make you "less" drunk eventually, but it slows the spike.
How Long Can You Stay Drunk: The Timeline
If we're talking about the "feeling" of being drunk—the euphoria, the lack of coordination, the questionable decision-making—you’re usually looking at a window of 4 to 10 hours.
But that's a massive range.
If you hit a Blood Alcohol Concentration (BAC) of 0.15 (nearly double the legal limit in most places), and your body clears about 0.015 per hour, you are looking at ten hours just to get back to zero. But "zero" on a breathalyzer isn't the same as being "back to normal."
The Hangover vs. The Buzz
There is a weird gray area. It’s that moment when your BAC hits 0.00 but you still feel like a train hit you. This is the hangover phase. Is this "staying drunk"? Technically, no. Functionally? You’re still impaired.

Studies from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) show that cognitive deficits—like poor memory and slow reaction times—persist long after the alcohol is physically gone. Your brain is still inflamed. Your electrolytes are a mess. Your glutamate levels are rebounding, making you anxious and "jumpy."
The Myth of Sobbing Up Fast
Let's kill the myths. Honestly, they’re dangerous.
- Coffee: It just creates a "wide-awake drunk." You’re still uncoordinated, you’re just faster at it.
- Cold Showers: This just gives you a shock. It might wake you up, but it doesn't change your BAC.
- Bread/Carbs: Eating after you’re already drunk is like closing the barn door after the horse has bolted. The alcohol is already in your blood.
- Exercise: You might sweat out a tiny, negligible amount of alcohol, but your liver does 90% of the heavy lifting. You can’t outrun a bottle of tequila.
Detection Windows: It Stays Longer Than You Think
Even when you feel sober, the evidence lingers. This is where people get caught in legal or workplace trouble.
- Breath: Usually detectable for up to 24 hours depending on the device's sensitivity.
- Urine: Standard tests look for metabolites like ethyl glucuronide (EtG). These can show up 12 to 48 hours later. Some advanced tests claim up to 80 hours.
- Hair: This is the long game. Alcohol markers can stay in your hair for up to 90 days.
- Blood: Generally 6 to 12 hours, as blood is the first place it clears from.
The Danger of "The Morning After"
This is where the question of how long can you stay drunk becomes a safety issue. Thousands of people drive to work on Monday morning still technically intoxicated from Sunday night.
If you stopped drinking at midnight but had a "big night" (maybe 8-10 drinks), you could easily still be at a 0.04 or 0.05 at 8:00 AM. In some jurisdictions, or for commercial drivers, that’s a violation. Your brain's processing speed is still lagged. You’re more likely to miss a red light or misjudge a turn.
Actionable Steps for Recovery
If you find yourself asking how long can you stay drunk because you're currently in the thick of it, there are a few things that actually help the recovery process, even if they don't "sober you up" instantly.

Hydrate with Electrolytes
Don't just chug plain water. Your body needs sodium, potassium, and magnesium to process the toxins. Reach for a sports drink, coconut water, or a dedicated rehydration salt.
Vitamin B6 and B12
Alcohol depletes B vitamins rapidly. Taking a B-complex or eating foods rich in them (like eggs) can help your brain start the repair process.
Sleep is the Only Real Cure
Your body does its best metabolic work while you’re out. However, alcohol-induced sleep is usually poor quality. It disrupts REM cycles. Expect to feel groggy, but stay in bed as long as you can to let the liver finish the "hallway" of alcohol.
Check Your Medications
If you're still feeling the effects, avoid Tylenol (Acetaminophen). Your liver is already stressed from the alcohol; adding Tylenol can lead to serious liver damage. Stick to Ibuprofen if you have a headache, but be careful as it can irritate an already sensitive stomach lining.
Monitor Your Heart Rate
If you feel your heart racing or "skipping a beat" (Holiday Heart Syndrome), or if you experience extreme confusion, seek medical help. Alcohol poisoning is a sliding scale, and sometimes "staying drunk" for too long is a sign your body is overwhelmed.
The reality is that your body is a slow processor. There are no shortcuts. If you’ve had a heavy night, give yourself a full 24 hours before you assume you’re back to 100% capacity. Your liver is working hard; don't make its job any tougher.
