Whether you have one drink or three (or more), you are always at risk for a hangover depending on your gender, body weight and experience with alcohol. There are many things you can do to decrease your chances of getting hangover, including not drinking any alcohol. But some people don’t want to go that route.
One way to cut your risk or severity of the hangover is to lower the amount of congeners you take in. Congeners are the by-products of fermentation of alcohol and the darker the alcohol higher the congeners. So, alcohol like red wine, whiskey, tequila, brandy, and bourbon, contain more congeners than gin or vodka.
Some people may not notice a difference between light rum and dark rum, but the difference is there. The dark rum has more congeners than the light rum and the dark rum increases your risk of hangover.
