Christmas means a lot of celebrations, and celebrations mean a lot of drinking. You'll probably throw caution to the wind ("It's just once a year, after all!"), but at the back of your mind, you know it won't feel good in the morning as you nurse a nasty hangover.

Hangovers occur when your body suffers dehydration while the alcohol levels of your blood slowly dip. Want to sidestep this morning-after experience? Read on for our tips. Want to know what to do if you’ve had too much to drink? We’ve got solutions for that, too. And as you attend each holiday get-together, know that how much you drink tonight will probably be directly proportional to how bad you'll feel the next day. Remember to pace yourself and drink moderately.
