No food, drink, or supplement has been shown to rapidly cure a hangover. NIAAA explains that the body needs time to clear alcohol-related byproducts, restore hydration, heal irritated tissues, and return brain and immune activity toward normal.
Eating and drinking can still be useful. They may relieve specific symptoms such as thirst, hunger, weakness, or stomach discomfort, but “I feel a little better” is not the same as “I eliminated alcohol faster.”
Water helps thirst, but it is not an antidote
Alcohol suppresses vasopressin and increases urination, which can contribute to mild dehydration. Drinking water afterward helps replace fluid and relieve thirst.
NIAAA emphasizes that dehydration is only one part of a hangover. Fragmented sleep, gastrointestinal irritation, inflammation, and acetaldehyde also contribute. Drinking a huge volume of water at once therefore does not “flush out” a hangover or accelerate brain recovery.
Gentle foods can help when you are hungry or nauseated
Toast, rice, bananas, yogurt, oatmeal, soup, or other simple foods may be easier to tolerate when the stomach is irritated. A normal meal containing carbohydrate, some protein, and fluid can help restore energy and routine.
There is no evidence that one famous combination — eggs, bacon, bananas, broth, or juice — neutralizes alcohol toxins. Choose foods you tolerate and avoid forcing down a very fatty meal if it worsens nausea.
Do you need electrolytes?
NIAAA says research has not found a clear relationship between the degree of electrolyte disruption and hangover severity, nor evidence that added electrolytes meaningfully reduce hangover symptoms for most people.
An electrolyte drink can be reasonable if you have been vomiting, sweating heavily, or simply find it easier to drink than water, but it is not a special cure. In most people, electrolyte balance returns as the effects of alcohol resolve.
Coffee may wake you up, but it does not sober you up
Caffeine can temporarily reduce sleepiness and, for habitual coffee drinkers, may prevent a caffeine-withdrawal headache. It does not lower blood alcohol concentration or speed alcohol metabolism.
Strong coffee can also worsen jitteriness or stomach irritation in some people. Drink it because it is part of your routine or feels comfortable, not as a way to make driving or work safe before recovery is complete.
More alcohol the next morning prolongs the problem
The “hair of the dog” may temporarily reduce some symptoms by raising blood alcohol again, but NIAAA warns that it can contribute to and prolong the hangover rather than cure it.
It can also reinforce a risky pattern of using alcohol to treat the consequences of alcohol. If a person needs morning alcohol to control shaking, severe anxiety, or illness after frequent heavy drinking, that may represent withdrawal rather than an ordinary hangover and can require medical care.
Use caution with pain relievers
NIAAA warns that alcohol plus acetaminophen can be toxic to the liver. Aspirin and ibuprofen can increase acid release and irritate the stomach lining, which may already be inflamed after drinking.
Automatically taking medication “just in case” before bed after drinking is therefore not a harmless universal strategy. People with liver disease, ulcers, medication interactions, or other relevant conditions should seek professional advice.
When is it more than a hangover?
Severe confusion, inability to wake, slow or irregular breathing, seizures, persistent vomiting, or unconsciousness can indicate serious alcohol poisoning and require urgent medical attention. In someone with prolonged heavy use, marked tremor, hallucinations, or seizures after stopping can reflect alcohol withdrawal, which can be dangerous.
The practical rule: drink fluids as tolerated, eat simple food if you are hungry, and rest. Do not expect coffee, electrolytes, cold showers, or more alcohol to remove the hangover. Time is what completes recovery, and the most reliable prevention is drinking less or not drinking.
The practical answer depends on method and context. One number can work well in one kitchen and poorly in another because of differences in equipment, temperature, portion size, or food. Use the first batch as calibration and change only one variable at a time to build your own repeatable reference.
Frequently asked questions
What drink cures a hangover?
None. Fluids can ease thirst, but only time allows the body to complete recovery.
Do electrolyte drinks work?
They can help with hydration, especially after vomiting, but NIAAA does not find evidence that they independently reduce hangover severity for most people.
Does coffee help?
It may improve alertness, but it does not speed alcohol clearance or cure a hangover.
