There’s no magic cure for a hangover, but you can speed up recovery and reduce the misery with a combination of rehydration, the right pain reliever, food, and rest. Hangover symptoms peak once your blood alcohol level drops back to zero and can last 24 hours or longer, so the goal is to support your body while it clears the toxic byproducts of alcohol metabolism.
Why You Feel So Terrible
Your liver breaks down alcohol into a compound called acetaldehyde, which is significantly more toxic than alcohol itself. Acetaldehyde triggers inflammation, irritates your stomach lining, and is responsible for much of the nausea, headache, and general awfulness of a hangover. Your body then converts acetaldehyde into a harmless substance and clears it, but that process takes time. About 40% of East Asian individuals carry a genetic variant that slows this conversion, which is why some people flush red and feel worse after even small amounts of alcohol.
On top of the toxic byproducts, alcohol suppresses a hormone that helps your kidneys retain water. That’s why you urinate so much while drinking. By morning, your electrolyte balance is disrupted: sodium and potassium levels shift, your blood sugar drops, and your body’s acid-base balance is off. The combination of dehydration, low blood sugar, inflammation, and poor sleep quality creates the full constellation of hangover symptoms.
Rehydrate, but Smarter Than Just Water
Drinking water helps, but plain water alone doesn’t replace the sodium and potassium your body lost overnight. An electrolyte drink, coconut water, or even broth will restore those minerals faster. In one study of moderate drinkers, participants consumed about 1,300 ml of fluid during an evening of drinking but only 400 ml the next morning, which isn’t nearly enough to offset the diuresis from the night before.
A practical approach: drink a full glass of water or an electrolyte beverage before bed, and another when you wake up. Sip steadily through the morning rather than chugging large amounts at once, which can make nausea worse.
Eat Something, Even If You Don’t Want To
Alcohol lowers your blood sugar, and that drop contributes to the shakiness, fatigue, and brain fog of a hangover. Eating carbohydrate-rich foods helps bring your glucose back up. The classic BRAT foods (bananas, rice, applesauce, toast) are gentle on an irritated stomach while delivering the carbs and potassium you need. Eggs are another solid option because they contain an amino acid that helps your liver process acetaldehyde.
You don’t need a huge meal. Even a few bites of toast or a banana can stabilize your blood sugar enough to take the edge off. If nausea is severe, start with small sips of broth and work up to solid food as your stomach settles.
Choose Your Pain Reliever Carefully
A headache is usually the most disruptive hangover symptom, and an over-the-counter pain reliever can help. But not all options are equally safe after drinking.
- Ibuprofen works well for headache and inflammation, but it can irritate a stomach that’s already inflamed from alcohol. Take it with food, not on an empty stomach.
- Aspirin carries the same stomach irritation risk as ibuprofen. If your stomach is sensitive, skip it.
- Acetaminophen (Tylenol) is the one to avoid. Alcohol activates the same liver enzyme responsible for converting acetaminophen into a toxic byproduct. This enzyme, already revved up from processing alcohol, produces more of that harmful metabolite than it normally would, raising the risk of liver damage. This isn’t a theoretical concern. Animal studies show that removing this enzyme almost entirely protects against acetaminophen’s liver toxicity.
If your stomach can handle it, ibuprofen taken with food and water is generally the safest bet for hangover headache relief.
What Your Drink Choice Had to Do With It
Not all alcohol produces equally bad hangovers. Dark spirits like bourbon, rum, and scotch contain higher levels of congeners, which are chemical byproducts of fermentation that your body has to process alongside the alcohol itself. Bourbon is particularly high in isobutanol (400 to 600 mg/ml compared to about 200 mg/ml in scotch). Rum and some bourbons are also high in acetaldehyde, the same toxic compound your liver produces when breaking down ethanol.
Vodka is considered the “cleanest” spirit, with the fewest congeners. This doesn’t mean vodka hangovers don’t happen, but if you drank the same amount of alcohol as bourbon, vodka would typically leave you feeling less terrible the next day. Worth remembering for next time.
Skip the “Hair of the Dog”
Drinking more alcohol the next morning is one of the oldest hangover “remedies,” and it does temporarily make you feel better. That’s because a hangover develops as your blood alcohol drops sharply after you stop drinking. Adding alcohol back into your system masks the symptoms by reversing that drop. But it doesn’t fix anything. It just delays the hangover until later, and you’ll likely feel worse when it finally catches up because your liver has even more alcohol to process.
Supplements and Hangover Products
The supplement industry sells dozens of hangover pills and powders, many claiming to prevent or cure hangovers with B-vitamins, zinc, or herbal extracts. A systematic review of 82 commercially available hangover products found no peer-reviewed human data demonstrating either safety or efficacy for any of them.
One exception that has some research behind it is prickly pear extract (from the Opuntia ficus-indica cactus). A study published in JAMA Internal Medicine found that taking 1,600 IU of prickly pear extract on an empty stomach about five hours before drinking reduced some markers of hangover inflammation. However, this is a prevention strategy, not a cure. Taking it the morning after won’t help, and the results were modest enough that researchers stopped short of calling it a reliable solution.
The Recovery Timeline
Most hangovers follow a predictable arc. Symptoms are worst in the first few hours after your blood alcohol hits zero, which for a night of heavy drinking is typically mid-morning. From there, you’ll gradually improve over the course of 12 to 24 hours as your body clears acetaldehyde, restores electrolyte balance, and brings inflammation down.
The most effective thing you can do is also the least exciting: sleep. Alcohol disrupts your sleep architecture, cutting into the deep, restorative stages your brain needs. Even if you were in bed for eight hours, you likely didn’t get quality rest. A nap in the afternoon, after you’ve eaten and rehydrated, can accelerate recovery more than any pill on the market.
What Actually Works, Summarized
- Electrolyte fluids before bed and throughout the next day to restore sodium and potassium.
- Carbohydrate-rich food like toast, bananas, or rice to bring blood sugar back up.
- Ibuprofen with food for headache, avoiding acetaminophen entirely.
- Sleep to make up for the poor quality rest alcohol causes.
- Time. Your liver processes alcohol at a fixed rate, and no supplement changes that.
The only guaranteed way to avoid a hangover is to drink less. Spacing drinks out, alternating with water, eating before and during drinking, and choosing lower-congener spirits all reduce the severity of what you’ll feel the next day. None of that helps much right now if you’re reading this with a pounding headache, but your body is already doing the hard work of recovery. Give it the water, food, and rest it needs, and you’ll get through it.
