A hangover fades on its own as your body finishes processing alcohol, but the right steps can ease symptoms significantly while you wait. Most hangovers peak once your blood alcohol level drops back to zero and can last 24 hours or longer. There’s no instant cure, but targeting the specific things making you feel terrible (dehydration, inflammation, low blood sugar, and toxic byproducts) makes a real difference.
Why You Feel This Bad
A hangover isn’t just dehydration, though that’s part of it. Your liver breaks alcohol down into a compound with properties similar to formaldehyde, which contributes directly to headache and nausea. At the same time, alcohol triggers your immune system to release inflammatory molecules called cytokines, and their levels in your blood the night before are directly linked to how rough the next morning feels.
On top of that, your liver was so busy processing alcohol that it slowed down its normal job of releasing glucose into your bloodstream. If you drank on an empty stomach or didn’t eat much beforehand, your blood sugar likely dropped. That’s a big reason for the shakiness, fatigue, and brain fog. Understanding these overlapping causes explains why no single remedy fixes everything, and why a combination approach works best.
Rehydrate With More Than Water
Alcohol is a diuretic, so you’ve lost more fluid than usual. Plain water helps, but adding electrolytes speeds things up. Sports drinks, electrolyte packets, or even broth replace the sodium and potassium you’ve lost along with the water. Your body absorbs fluid faster when electrolytes are present, so you’ll notice a difference sooner than with water alone.
Aim to drink steadily rather than chugging a huge amount at once, which can trigger more nausea. Broth is a particularly good option because it delivers sodium, some calories, and is easy on a sensitive stomach.
Eat the Right Foods
Your blood sugar needs restoring. Bland, carbohydrate-rich foods like toast, crackers, or oatmeal give your body the glucose it’s been missing. Bananas are helpful because they’re gentle on the stomach and contain potassium, which drops during heavy drinking.
Eggs deserve special mention. They’re rich in an amino acid called cysteine, which your body uses to produce glutathione, a key antioxidant involved in breaking down toxic alcohol byproducts. Drinking depletes your glutathione stores, and eating eggs helps rebuild them. A simple plate of eggs and toast addresses both blood sugar and detoxification at once.
Choose the Right Pain Reliever
For a pounding headache, ibuprofen or naproxen (anti-inflammatory options) can help reduce the inflammation driving your symptoms. However, these can irritate your stomach, which may already be sensitive, and they carry some liver risk when combined with alcohol still in your system.
Acetaminophen (Tylenol) is often considered safer for the liver at proper doses, but the combination of acetaminophen and recent heavy drinking puts extra strain on the same liver pathways. If you choose acetaminophen, keep the dose low. Neither option is risk-free the morning after drinking, so take the minimum effective dose with food and water.
Skip the Coffee
Reaching for coffee feels instinctive, but it can backfire. Coffee is a diuretic, meaning it makes you urinate more and can slow down your rehydration. Caffeine also narrows blood vessels and raises blood pressure, which can amplify a headache rather than relieve it. If you’re a daily coffee drinker and skipping it would give you a caffeine withdrawal headache on top of everything else, a small amount is reasonable. But don’t count on coffee as a hangover fix.
Supplements That May Help
Dihydromyricetin (DHM), a compound extracted from the Japanese raisin tree, has shown promise in research. It triggers the liver to produce more of the enzymes that break down alcohol and its toxic byproducts, boosts the efficiency of those enzymes, and reduces inflammatory cytokines. Research from USC found it also reduced fat accumulation in liver tissue. DHM supplements are widely available, though most of the strong evidence comes from animal studies so far.
Ginger, whether in tea, capsules, or ginger ale made with real ginger, is a well-established anti-nausea remedy and can settle your stomach while you recover.
What Your Drink Choice Has to Do With It
Not all alcohol punishes you equally. Darker drinks like bourbon, brandy, red wine, and whiskey contain higher levels of congeners, chemical byproducts of fermentation that worsen hangovers. Vodka and beer contain the least. In one study, people who drank bourbon reported significantly worse hangovers than people who drank the same amount of vodka, reaching the same peak blood alcohol level. This won’t help you right now, but it’s worth remembering next time.
Don’t Drink More Alcohol
“Hair of the dog” is one of the most persistent hangover myths, and it doesn’t work. Drinking more alcohol the next morning masks your symptoms temporarily by putting alcohol back into your system, but the hangover returns once that new dose wears off. Your liver processes alcohol at a fixed rate of roughly one drink per hour, and nothing speeds that up. Drinking more just delays recovery and adds to the total load your body has to clear.
What a Realistic Recovery Looks Like
Hangover symptoms peak once your blood alcohol concentration hits zero, which is why you sometimes feel fine going to bed and miserable waking up. From that peak, most people start improving within 12 hours, though symptoms can persist for a full 24 hours or longer after heavy drinking.
The most effective recovery plan combines several approaches: steady hydration with electrolytes, food that restores blood sugar and supports your liver (eggs, toast, bananas), a cautious dose of an anti-inflammatory if your headache is severe, rest, and time. None of these is a miracle cure individually, but together they address the dehydration, inflammation, low blood sugar, and toxic buildup that are all happening simultaneously. Your body is already doing the hard work of clearing everything out. The goal is to stop making things worse and give it what it needs to finish the job.
