While a hangover has many components, what you drink can impact your hangover. I have found drinking healthy alcoholic drinks have reduced my hangovers. When I mean healthy is higher quality drinks with better ingredients.
The ingredients in the alcohol you drink can affect your hangover. Drinks with higher levels of congeners or hops can worsen a hangover. Hops give beer its bitter, crisp taste, but can be hard on the body.
Congeners are a by-product of the process of alcohol fermentation and can exaggerate the symptoms of a hangover. Dark spirits like brandy, whiskey, and red wine contain more congeners than lighter spirits like vodka and white wine.
So I recommend drinking healthy alcoholic drinks such as vodka and club soda with fruit. If that is too bland whiskey and water is not a terrible option even though whiskey does have some congeners. But the water is a healthy mixer
