A hangover is a group of unpleasant signs and symptoms that can develop after drinking too much alcohol. The more alcohol you drink, the more likely you are to have a hangover the next day. But there's no magic formula to tell you how much you can safely drink yet still avoid a hangover.

However unpleasant, most hangovers go away on their own within 24 hours. If you choose to drink alcohol, doing so responsibly can help you avoid future hangovers.
