The best thing for a hangover is a combination of rehydration, food, rest, and time. There’s no single cure that eliminates hangover symptoms instantly, but several strategies meaningfully reduce how bad you feel and how long it lasts. Hangover symptoms peak once your blood alcohol level drops back to zero and can persist for 24 hours or longer, so the goal is to support your body’s recovery process rather than try to shortcut it.
Why Hangovers Feel So Terrible
Understanding what’s actually happening in your body helps explain why certain remedies work and others don’t. When you drink, your liver breaks alcohol down into a toxic compound called acetaldehyde, which is then converted into a relatively harmless substance called acetate. If you drink faster than your liver can keep up, these byproducts accumulate. Acetate, in particular, appears to trigger the headache component of a hangover by activating pain pathways in the head and face.
Alcohol also triggers a measurable inflammatory response. Blood levels of specific inflammatory markers rise after heavy drinking, and those levels correlate directly with how severe the hangover feels the next day. On top of that, alcohol suppresses the hormone that tells your kidneys to hold onto water, so you lose more fluid than you take in. The result is a combination of dehydration, inflammation, and metabolic stress that produces the familiar headache, nausea, fatigue, and brain fog.
Start With Fluids, but Choose Wisely
Water is your first priority. A glass as soon as you wake up begins reversing the dehydration that accumulated overnight. But if you vomited during or after drinking, plain water may not be enough. Vomiting depletes sodium, potassium, and other electrolytes that water alone won’t replace. In that case, an electrolyte drink like Pedialyte or a sports drink does a better job of restoring what you’ve lost.
Alternating water with alcoholic drinks the night before is one of the simplest and most effective prevention strategies, since it slows both your alcohol intake and fluid loss in real time.
What to Eat (and Why Eggs Are a Good Call)
Eating before or while drinking slows alcohol absorption, which reduces the metabolic burden on your liver. The morning after, food helps stabilize blood sugar, which alcohol disrupts. Toast, bananas, and oatmeal are gentle options if your stomach is sensitive.
Eggs deserve special mention. They’re rich in an amino acid called L-cysteine, which helps your body process acetaldehyde, the toxic intermediate your liver produces when breaking down alcohol. Cysteine binds to acetaldehyde and helps neutralize it. This isn’t a dramatic cure, but it’s a biologically sound reason to choose eggs over other breakfast options when you’re hungover.
Fruit juice and honey contain fructose, a natural sugar that may speed up alcohol clearance. In lab studies, fructose increased the rate of alcohol breakdown by more than 50%. The effect in humans is more modest, but a glass of orange juice or a spoonful of honey in tea still offers hydration, sugar for low blood glucose, and vitamins, making it a reasonable addition to your recovery plan.
Pain Relievers: Proceed With Caution
Reaching for a painkiller is one of the most common hangover responses, but the choice matters more than most people realize. Acetaminophen (Tylenol) is risky after drinking because both alcohol and acetaminophen are processed by the liver. When the liver is already taxed from breaking down alcohol, acetaminophen can cause serious liver damage, even at normal doses.
Ibuprofen (Advil, Motrin) has long been considered the safer alternative, but newer research complicates that picture. A study examining liver cells found that ibuprofen and alcohol together produced synergistic liver toxicity, meaning the combined damage was worse than either substance alone. The mechanism involves a surge in oxidative stress that overwhelms the liver’s defenses.
If you do take a pain reliever, ibuprofen is still generally considered the lesser risk compared to acetaminophen after drinking. But waiting until your body has had time to process most of the alcohol, and taking it with food, reduces the potential for harm. Aspirin is another option, though it can irritate an already-sensitive stomach.
Supplements and Herbal Remedies
A growing market of hangover supplements lines pharmacy shelves, most containing some combination of vitamins, minerals, milk thistle, and other herbal extracts. The evidence behind most of them is thin. A review of commercially available hangover products found that nearly half contained a plant compound called dihydromyricetin (DHM) and a similar proportion included N-acetyl cysteine (NAC), but none provided clinical studies demonstrating that their specific formulations actually work.
NAC, which is a supplemental form of the same cysteine found in eggs, has a plausible mechanism of action as an antioxidant. However, a clinical study that gave participants 1.2 grams of NAC both before and after binge drinking found it had no measurable effect on oxidative stress markers or hangover symptoms. The theory is better than the results, at least at the doses tested.
Red ginseng has slightly more promising data behind it. A randomized crossover study in 25 healthy men found that a red ginseng drink significantly lowered blood alcohol levels at 30, 45, and 60 minutes after drinking compared to a placebo. The ginseng group also reported less severe hangover symptoms overall. The study was small, but the results were consistent across multiple measurements.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol the next morning, delays your hangover rather than treating it. It temporarily raises your blood alcohol level, which masks symptoms, but you’ll feel worse once that additional alcohol is metabolized. It also increases your total toxic load and can establish a pattern that edges toward dependence.
Coffee helps with the fatigue and grogginess, but it’s a diuretic that can worsen dehydration. If you drink coffee, match it with an equal or greater amount of water.
Greasy food the morning after is a comfort, but it doesn’t “absorb” alcohol that’s already in your bloodstream. Eating greasy food before drinking can slow absorption, which is useful. The next morning, it’s more likely to upset an already irritated stomach.
The Recovery Timeline
Hangover symptoms hit their worst point right around when your blood alcohol returns to zero, which for most people is sometime in the early to mid-morning after a night of heavy drinking. From that peak, symptoms gradually decline but can linger for a full 24 hours or longer depending on how much you drank, your body size, your hydration status, and how well you slept.
Sleep itself is one of the most effective recovery tools. Alcohol disrupts sleep architecture, reducing the restorative deep sleep your body needs to repair itself. Napping the next day, if you can, gives your body a second chance at the recovery sleep it missed overnight.
The Most Effective Strategy Is Prevention
No remedy after the fact works as well as moderating intake in the first place. Drinking on a full stomach, pacing yourself to roughly one drink per hour, choosing lighter-colored liquors (which contain fewer congeners, the fermentation byproducts that worsen hangovers), and drinking water between rounds all reduce next-day severity. These aren’t dramatic interventions, but they’re more reliable than anything you can take the morning after.
