9. Water

Water is a major element in staying healthy. And yet people tend to ignore it after meals and prefer to drink alcohol. Alcohol is also fine as long as you keep it to a limit. But when you exceed your limit, you end up with hangovers. A major contributor to hangovers is the lack of water in the body. So if you drink a good amount of water before going to bed while drunk, then the symptoms of a hangover is likely to be reduced. You won’t need to take painkillers which have problems of their own.
