Prevention is the best cure for a hangover. The only way to avoid a pounding head and queasiness the morning after is to drink in moderation, or to stay away from alcohol entirely. But with all sorts of seasonal celebrations going on, it's easy to overindulge.
Alternating your drinks with water or another nonalcoholic beverage can help you slow down and stay hydrated. If you still wind up with a hangover, you may be inclined to try one of the many supposedly tried-and-true remedies that have been passed down through the ages.
Don't get your hopes up. Traditional hangover remedies are often ineffective, and some of them may actually make you feel worse.
