There is no true cure for a hangover. Your body needs time to break down alcohol and clear its toxic byproducts, and no pill, drink, or home remedy can speed that process up in a meaningful way. Most hangovers resolve within 24 hours on their own. What you can do is reduce the severity of specific symptoms and help your body recover more comfortably while it does its work.
Why You Feel This Bad
When you drink, your liver converts alcohol into a compound called acetaldehyde, which is highly toxic and classified as a carcinogen. Acetaldehyde is normally broken down quickly into a harmless substance your body can eliminate, but when you drink heavily, the system gets backed up. That toxic intermediate builds up, and it contributes directly to nausea, headache, and the general feeling of being poisoned, because you were.
Alcohol also triggers inflammation throughout your body by raising levels of immune signaling molecules called cytokines. These are the same chemicals your body releases when you’re fighting an infection, which is why a bad hangover can feel eerily similar to the flu. On top of that, alcohol suppresses a hormone that tells your kidneys to retain water, so you urinate far more than you normally would. The result is dehydration and a loss of electrolytes like sodium and potassium, which contribute to dizziness, fatigue, and that pounding headache.
Rehydration: Water vs. Electrolyte Drinks
Replacing lost fluids is the single most helpful thing you can do. Plain water works, but it has a limitation: it doesn’t contain electrolytes. Without enough sodium, your kidneys flush out much of what you just drank instead of absorbing it. An oral rehydration solution like Pedialyte uses a precise ratio of sugar and salt that pulls fluid into your bloodstream faster than water alone and helps your body actually hold onto it. Sports drinks fall somewhere in between, though many contain more sugar than is ideal for absorption.
If you don’t have an electrolyte drink on hand, you can approximate the effect by sipping water alongside something salty, like broth or a few crackers. The goal is steady intake over a couple of hours, not chugging a liter all at once, which can make nausea worse.
What to Eat (and Why Eggs Help)
Eating might be the last thing you want to do, but bland, easy-to-digest food gives your body fuel for recovery and helps stabilize blood sugar, which drops after heavy drinking. Toast, bananas, rice, and oatmeal are all reasonable choices.
Eggs deserve a special mention. They’re rich in an amino acid called L-cysteine, which binds directly to acetaldehyde, the toxic byproduct your liver is struggling to clear. Research has shown that L-cysteine reduces hangover-related nausea, headache, stress, and anxiety. It also has antioxidant properties that help counteract the oxidative damage alcohol causes to your cells. You don’t need a supplement for this. A couple of scrambled eggs deliver a meaningful dose.
Fruit can also help. The natural sugars in fruit provide quick energy for your liver’s metabolic processes, and the water content contributes to rehydration. Bananas are especially useful because they’re high in potassium, one of the electrolytes you lose most when drinking.
Pain Relievers: Choose Carefully
Reaching for a painkiller is reasonable, but your choice matters. Ibuprofen (Advil, Motrin) or naproxen (Aleve) can help with headache and body aches. However, these are harder on your stomach lining, which is already irritated from alcohol. If your hangover leans heavily toward nausea and stomach pain, they can make things worse.
Acetaminophen (Tylenol) is the one to avoid. It’s processed by the same liver pathways that are already overloaded from breaking down alcohol. While it’s safe at proper doses under normal conditions, combining it with alcohol significantly increases the risk of liver damage. If you’ve been drinking heavily in the past 24 hours, skip it entirely.
Supplements That Have Some Evidence
Most “hangover cure” supplements are marketing with little science behind them, but a couple of ingredients have shown real effects in studies.
Prickly pear extract, taken before drinking, reduced the risk of a severe hangover by roughly half in a study published in JAMA Internal Medicine. Three symptoms improved significantly: nausea, dry mouth, and loss of appetite. The catch is that it works as a preventive measure, not a morning-after fix. If you didn’t take it before you started drinking, it won’t help now.
Dihydromyricetin (DHM), a compound derived from the Japanese raisin tree, is the active ingredient in several popular hangover supplements. It has strong antioxidant and anti-inflammatory properties and has shown protective effects on the liver in animal studies, reducing alcohol-induced fat buildup and inflammation. It’s widely available and generally marketed for use before, during, and after drinking. Human clinical evidence is still limited compared to the animal data, so manage your expectations, but it’s one of the more promising options on the market.
What Won’t Help
Coffee might make you feel more alert, but it doesn’t speed up alcohol metabolism and can worsen dehydration. “Hair of the dog,” or drinking more alcohol, temporarily masks symptoms by re-introducing the substance your body is trying to clear. It delays recovery and can set up a cycle of dependence over time.
IV drip bars have become popular in some cities, offering intravenous fluids and vitamins marketed as hangover cures. They rehydrate you efficiently, but there’s no evidence they resolve hangover symptoms faster than drinking electrolyte solutions by mouth. You’re mostly paying for the placebo of feeling like you’re receiving medical treatment.
Prevention Makes the Biggest Difference
The most effective hangover strategy happens before you feel sick. Eating a full meal before drinking reduces peak blood alcohol levels substantially. One study found that eating a meal before drinking reduced the amount of alcohol available for absorption to only 66-71%, compared to near-complete absorption on an empty stomach. Peak blood alcohol concentration dropped by about 30% in people who ate a full meal versus those who fasted. Lower peak levels mean less acetaldehyde buildup and a milder morning.
What you drink also matters. Dark liquors like bourbon, brandy, cognac, and red wine contain high levels of congeners, chemical byproducts of fermentation that worsen hangovers. Methanol, one of the most problematic congeners, is found in the greatest quantities in dark spirits and breaks down into formaldehyde and formic acid in your body. Clear drinks like vodka, gin, white wine, and light beer contain far fewer congeners. Choosing lighter-colored drinks won’t prevent a hangover if you drink enough, but it does reduce the chemical burden your body has to deal with the next day.
Alternating alcoholic drinks with glasses of water slows your intake and reduces dehydration simultaneously. It’s simple, free, and more effective than any supplement you can buy.
