There’s no instant cure for a hangover, but you can speed up your recovery by tackling the specific things making you feel terrible: dehydration, inflammation, poor sleep, and the toxic byproducts your liver is still processing. Most hangovers resolve within 24 hours, and the strategies below can shorten that window meaningfully.
Why You Feel This Bad
When your liver breaks down alcohol, it first converts it into a compound called acetaldehyde, which is significantly more toxic than alcohol itself. A second enzyme then clears acetaldehyde from your system. If you drank more than your liver could process at its steady rate of about one standard drink per hour, acetaldehyde built up in your bloodstream. That backlog is responsible for much of the nausea, facial flushing, and overall misery you’re experiencing right now.
On top of that, alcohol triggers an inflammatory response throughout your body, similar to what happens when you’re fighting off an infection. That inflammation contributes to the headache, muscle aches, and brain fog. Alcohol also suppresses deep, restorative sleep during the second half of the night. Even if you slept for eight hours, your brain cycled through far more wake periods than normal, and you got less REM sleep than your body needed. The result is that groggy, can’t-think-straight feeling layered on top of everything else.
Rehydrate With Electrolytes, Not Just Water
Alcohol is a diuretic, meaning it made you lose more fluid than you took in. Plain water helps, but electrolyte drinks are more effective at reversing dehydration because the minerals help your body actually retain the fluid rather than just passing it through. A drink with sodium, potassium, and a small amount of sugar (like an oral rehydration solution or a sports drink) will rehydrate you faster than water alone.
Sip steadily rather than chugging. If your stomach is already upset, flooding it with a large volume of liquid at once can make nausea worse. Small, frequent sips over the first hour or two will get fluid into your system without overwhelming your gut.
Take the Right Pain Reliever
Ibuprofen or aspirin can help with your headache and the general inflammatory aches. Both work by reducing inflammation, which is a core driver of hangover symptoms.
Avoid acetaminophen (Tylenol). Your liver uses the same protective molecule, glutathione, to process both acetaminophen and alcohol. After a night of heavy drinking, your glutathione stores are already depleted. Adding acetaminophen on top of that forces your liver to work without its safety net, increasing the risk of liver damage. Acetaminophen toxicity accounts for nearly half of acute liver failure cases in North America, and combining it with alcohol is one of the most common ways people accidentally push past safe limits.
One caveat with ibuprofen and aspirin: both can irritate your stomach lining, and alcohol has already done a number on it. Take them with food if possible, not on a completely empty stomach.
Eat Something, Even If You Don’t Want To
Food serves two purposes right now. First, it gives your body glucose, which alcohol metabolism depletes. Low blood sugar contributes to the shakiness, weakness, and irritability you might be feeling. Second, having something in your stomach makes it safer to take an anti-inflammatory pain reliever.
You don’t need anything fancy. Toast, crackers, bananas, eggs, or oatmeal all work. Bananas are particularly useful because they’re rich in potassium, one of the electrolytes you lost overnight. Eggs contain an amino acid that helps your body produce more glutathione, the same liver-protecting molecule that got depleted while processing alcohol. If you can manage a full meal, go for it. If not, even a few bites of bland carbs will help stabilize your blood sugar.
Sleep More If You Can
Alcohol sedates you into sleep quickly but then fragments it badly. During the second half of the night, your brain spends more time in light sleep and wakefulness, and REM sleep gets suppressed. Once your blood alcohol level drops, REM sleep can rebound, but by then the damage to your overall sleep quality is done.
If your schedule allows it, going back to sleep for even 90 minutes to two hours gives your brain a chance to get some of the restorative sleep it missed. This single step often does more for the cognitive fog, irritability, and fatigue than anything else. Keep the room cool and dark, and set an alarm if you’re worried about sleeping too long. Even a short nap later in the day can help if a full sleep session isn’t possible in the morning.
What About IV Drips and Hangover Clinics?
Hangover IV services have become popular, typically offering a bag of fluids, electrolytes, vitamins, and sometimes anti-nausea medication delivered through an IV line. The honest assessment from physicians at the University of Rochester: they might help, but they’re rarely necessary. IV fluids are generally reserved for people who genuinely cannot keep water down. If you can drink fluids orally, your body will absorb them effectively on its own.
IV drips also carry small risks. Starting an IV without checking bloodwork can be problematic for some people, and the cost (often $150 to $300) buys you something you could replicate at home with an electrolyte drink, a pain reliever, and rest. Save the IV clinic for a situation where vomiting has made it truly impossible to keep anything down for several hours.
The Timeline for Feeling Normal
Your liver clears alcohol at a fixed rate of roughly one standard drink per hour. If you had eight drinks and stopped at midnight, your body likely finished processing the alcohol itself around 8 a.m. But hangover symptoms typically peak after your blood alcohol level hits zero, not before. That’s because the inflammatory response and acetaldehyde damage linger after the alcohol is gone.
For a moderate hangover (four to six drinks the night before), most people feel substantially better within 12 hours of their last drink and back to normal within 18 to 24 hours. A heavier night can stretch that to a full 24 to 36 hours. Every hour that passes is your body clearing toxins and reducing inflammation, so the trajectory is always toward improvement even when it feels painfully slow.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol in the morning, delays your hangover rather than curing it. You’re essentially restarting the cycle and asking your liver to process even more toxins. Coffee can help with alertness but worsens dehydration and can amplify stomach irritation. If you drink coffee, pair it with extra water and food.
Greasy food is a popular hangover ritual, but it doesn’t absorb alcohol or speed recovery in any meaningful way. It can actually make nausea worse. Bland, easy-to-digest food is a better bet when your stomach is already inflamed.
Reducing Severity Next Time
The single strongest predictor of hangover severity is total alcohol consumed. Nothing else comes close. That said, some types of alcohol contain higher levels of congeners, which are chemical byproducts of fermentation that add flavor and color but also worsen hangovers. Darker spirits like bourbon and whiskey have more congeners than lighter options like vodka or gin. Interestingly, research from the Society for the Study of Addiction found that wine was consistently associated with the highest hangover severity, while beer, cider, and spirits scored lower.
Alternating alcoholic drinks with water throughout the night, eating a full meal before drinking, and pacing yourself to stay closer to that one-drink-per-hour metabolism rate are the most reliable ways to wake up feeling human the next morning.
