No single pill or drink cures a hangover, but several over-the-counter options, foods, and supplements can meaningfully reduce the headache, nausea, and fatigue while your body clears the remaining alcohol byproducts. The only guaranteed way to avoid a hangover is to drink less, but once you’re already feeling rough, the right combination of pain relief, hydration, and food can cut your recovery time significantly.
Pain Relievers: What Works and What to Avoid
Ibuprofen (Advil, Motrin) is the most commonly recommended pain reliever for a hangover headache. It reduces inflammation and works within 30 to 60 minutes. Aspirin works similarly but is slightly harsher on an already irritated stomach. Both are reasonable choices, though taking either on a completely empty stomach can cause nausea or gastric irritation, so eat something first if you can.
Acetaminophen (Tylenol) is the one to be cautious about. Your liver is already busy processing alcohol and its toxic byproduct, acetaldehyde. Adding acetaminophen forces your liver to handle yet another compound through the same detoxification pathway. Alcohol depletes a key protective molecule in the liver called glutathione, and without enough of it, acetaminophen byproducts can cause liver damage. If you drink heavily or regularly, the Cleveland Clinic recommends keeping acetaminophen below 2,000 mg per day, which is half the standard daily maximum. If you have any history of liver disease, skip it entirely.
Water and Electrolytes
Alcohol is a diuretic, meaning it causes your kidneys to flush more fluid than you’re taking in. By the morning after, you’re dehydrated, and that dehydration drives much of the headache, dizziness, and dry mouth. Plain water helps, but adding electrolytes speeds things up because you’ve also lost sodium, potassium, and magnesium overnight. Sports drinks, coconut water, or oral rehydration solutions like Pedialyte all work. Broth is another solid option since it delivers sodium along with fluid.
Aim to drink at least 16 to 24 ounces of fluid within the first hour of waking up, then keep sipping steadily. If you’re nauseous, small frequent sips are easier to keep down than chugging a full glass.
Food That Actually Helps
Alcohol disrupts your blood sugar regulation, and by morning your glucose levels may be lower than normal. That contributes to the shakiness, weakness, and brain fog that come with a hangover. The fix isn’t sugary cereal or juice, which will spike your blood sugar and then crash it again. Instead, go for complex carbohydrates paired with protein and a little fat.
Eggs are a popular hangover food for good reason. They contain an amino acid that supports the same liver detoxification pathway that alcohol taxes. Pair them with whole grain toast or oatmeal for steady energy. Other strong options include Greek yogurt with nuts, a sweet potato, or avocado toast with an egg on top. The combination of complex carbs, protein, and healthy fat slows digestion and creates a gradual, sustained rise in blood sugar rather than a spike and crash. Bananas are helpful too because they’re rich in potassium, easy on the stomach, and provide quick natural sugar alongside fiber.
B Vitamins
Alcohol depletes several B vitamins, particularly B1 (thiamine), B6, B12, and folate. These vitamins are essential for energy production and liver detoxification. A single night of heavy drinking won’t cause a dangerous deficiency, but topping up your levels can support your body’s recovery process. A standard B-complex supplement taken with food in the morning covers the bases. You’ll also get B vitamins from eggs, whole grains, leafy greens, and meat, so a solid breakfast does double duty.
Supplements Worth Knowing About
A few supplements have shown early promise for hangover relief, though none qualifies as a proven cure.
Dihydromyricetin (DHM) is extracted from the Japanese raisin tree and has become one of the more popular hangover supplements. It appears to support liver cell metabolism and protect against alcohol-related oxidative stress. It’s widely available in capsule form, often marketed as a “hangover pill.” Research is still in early phases, with a Phase I clinical trial currently studying its effects on alcohol-related liver changes. Many people take it before bed after drinking rather than the next morning.
Korean red ginseng has stronger clinical data behind it. A randomized, double-blind, placebo-controlled trial found that participants who took a red ginseng complex before drinking alcohol showed faster clearance of both alcohol and acetaldehyde from their blood. They also reported lower scores on two standardized hangover severity scales at both 6 and 15 hours after drinking. That’s a meaningful reduction in symptom duration. The catch is that, like DHM, it works best when taken before or during drinking rather than the next morning.
N-acetyl cysteine (NAC) is a precursor to glutathione, the same liver-protective compound that alcohol depletes. A clinical trial protocol tested NAC dosing at the end of a drinking session (one 600 mg capsule per three drinks consumed). The logic is sound: replenish glutathione before your liver runs out. NAC is widely available at pharmacies and supplement stores. Timing matters here too. Taking it after your last drink or before bed is more useful than waiting until you wake up symptomatic.
What Doesn’t Work
Coffee won’t cure a hangover. Caffeine may temporarily reduce the feeling of grogginess, but it’s also a mild diuretic, which can worsen dehydration. If you’re a regular coffee drinker and skipping it would give you a caffeine withdrawal headache on top of everything else, a small cup is fine. Just match it with extra water.
The “hair of the dog” approach, drinking more alcohol in the morning, delays your hangover rather than treating it. You’re simply restarting the cycle your liver needs to finish. Cold showers, greasy fast food, and activated charcoal have no reliable evidence behind them either. The NIAAA is blunt on this point: there is no cure for a hangover other than time.
A Practical Morning-After Plan
If you wake up hungover and want to recover as quickly as possible, here’s a reasonable sequence. Start with 16 to 20 ounces of water or an electrolyte drink. Take ibuprofen (not acetaminophen) if your headache is significant. Eat a meal built around complex carbs, protein, and fat within the first hour or two. A B-complex vitamin with that meal is a low-risk addition. Then keep hydrating steadily throughout the day.
Most hangovers peak within the first few hours after waking and resolve within 24 hours. Severe hangovers from very heavy drinking can last longer. If you’re experiencing persistent vomiting, confusion, or an irregular heartbeat, that’s beyond a standard hangover and warrants medical attention.
