Ok, it's New Year's Eve -- the one night where the whole world parties in unison, and chances are, you're going to be enjoying a few with friends and family, and as long as you do so safely, go for it! But nobody likes a bad hangover, so here are some things to keep in mind:

• EAT! It's not often that we tell you to eat more, but when you're drinking it's a must -- trust me, I've been there. If you drink on an empty stomach, you will feel 100 times worse tomorrow than you will if you ate a big meal.
  
• Alternate. Water is key to preventing a hangover so for every alcoholic beverage you have, have a glass of water.
  
• Stick to what you know. Mixing is killer, and so is pounding back shots. Stick to a drink you know doesn't make you ill -- clear liquids often do the trick. For me, beer is killer (especially from a keg) but white wine rarely gives me a hangover.
  
• Take Supplements. According to this eDiets article, taking vitamins B and C and Primrose oil before going to bed will help.
  
• Avoid taking Tylenol and Aspirin. But to take another painkiller to quell the throbbing headache.
