Hey, and welcome. Im a college student living w/three carboholics as well. haha. Gotta use that willpower to stay away from their food, and know u are donig something good for yourself. as far as drinking goes, those beers DO add up, even if htey are low carb. so stay away from them, or treat urself once a month. other than that, try to enjoy diet soda and rum, etc. you'll get used to it, and happier how u look at those parties anyways! (hehe!) hope some of this helped
