There is no set number of drinks that will cause a hangover. Everyone is different, but any time a person becomes intoxicated from alcohol, a hangover is possible.
There really is no way to cure a hangover fast. The only real cure for a hangover is time.
There are many remedies that claim to cure a hangover, but there is no scientific evidence that any of them work. The body needs to clear the toxic byproducts of alcohol metabolism, to rehydrate, to restore irritated tissue, and to return the immune system and brain activity to normal.
7 Hangover Home Remedies
However, while a hangover takes time to go away, there are some home remedies that may help ease symptoms. These include:
- Drinking plenty of fluids
- Alcohol can dehydrate you, so water or sports drinks can help restore fluid balance
- Eat foods with carbohydrates
- Drink coffee or tea
- These don’t technically help with the hangover but the caffeine may help with grogginess
- B vitamins and zinc
- Avoiding darker-colored alcoholic beverages
- This may help a little with prevention
- Clear liquors, such as vodka and gin, don’t tend to cause hangovers as frequently as dark liquors, such as whiskey, red wine, and tequila
- Take an over-the-counter (OTC) pain reliever
- This may help with headache and body aches
- Avoid acetaminophen (Tylenol) because any alcohol remaining in your system may add to acetaminophen's toxic effects on the liver
- Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin) and naproxen (Aleve) may be better choices, but they can increase acid production and worsen stomach irritation caused by drinking
- “Hair of the dog”
- Involves drinking a little more alcohol to ease symptoms of alcohol withdrawal
- It may work to minimize symptoms for a short time but it really doesn’t allow the body to recover properly
What Are Symptoms of a Hangover?
Symptoms of a hangover occur after drinking too much, can vary from person to person, can last 24 hours or longer, and may include:
- Muscle aches
- Stomach pain or discomfort
- Spinning sensation (vertigo)

What Causes a Hangover?
Drinking too much alcohol causes hangovers. Factors that can contribute to developing hangovers include:
- Problems sleeping
- Though people who are drunk may fall asleep faster, sleep is disrupted and they often wake up earlier
- Gastrointestinal irritation
- Acetaldehyde exposure
- Alcohol is primarily metabolized by the liver, which creates the compound acetaldehyde, a toxic, short-lived byproduct, that contributes to inflammation in the liver, pancreas, brain, gastrointestinal tract, and other organs
- People may feel relaxed and happy when drunk, but when the buzz wears off, restlessness and anxiety can occur
