What causes a 2 day hangover?

There are several factors that can lead to a two day long hangover.

Hydration Before, During, and After Drinking Alcohol

Drinking water or non-alcoholic beverages will prevent dehydration. This is vital to preventing hangovers since most hangover symptoms are exacerbated by dehydration. Try to drink a glass of water before drinking, between each alcoholic drink, and after drinking.

Amount of Alcohol Consumed

Generally, the more alcohol consumed, the longer the hangover will last.

Type of Alcohol Consumed

Different types of alcohol affect the body differently and they can even cause different hangover symptoms. For example, darker alcoholic drinks like whiskey and red wine contain byproducts of fermentation called congeners that can worsen the symptoms of a hangover.

Genetics and Tolerance

Some people may be more susceptible to hangovers than others due to their tolerance to alcohol and/or their genetics. 

Combining Other Substances with Alcohol

Mixing alcohol with other substances, such as drugs or energy drinks, can worsen the symptoms of a hangover and prolong its duration. 

Cocaine in particular can make hangovers last longer and feel worse. When cocaine and alcohol are consumed together, the liver combines them to form a substance called cocaethylene. Cocaethylene has a more potent effect on the cardiovascular and central nervous system than either substance alone, which can lead to increased risk of heart attack and stroke.
