These awnsers are hilarious. If you overdrink your main damage is to you--you get dehydrated, therefore you feel like crap. You get nauseous, you feel lethargic, and you can feel your heartbeat. However, if you chronically abuse alcohol, worry about your liver and your pancreas, not your heart. Those are the organs most effected by alcohol abuse. I m not saying have a drunken binge every once in awhile, we all do. But before you go to bed, try to drink a couple of glasses of water, take a motrin and brush your teeth. You ll feel better and the taste in your mouth won t make you want to vomit. Never take tylenol after drinking-it is also processed by your liver.
