It happens even when I have been smoking. I've never been a big eater, my old meds use to make me eat though, and so does weed. I have never touched crack and stopped doing coke a while ago. I think smoking might just help whatever my porblem seems to be. It really does suck. oh and I haven't smoked for I think 3 or 4 days and I have only eaten maybe 2 meals.....
