Hi Christine...I can appreciate the concern. I carry extra pounds around anyway and have been concerned about gaining and yes, the first week, I had to really curb the urge to open the fridge when I refused to light a smoke. I have been keeping Tootsie Roll Minis and Life Savers (the individually wrapped variety) around (night stand, end tables, purse, coat pockets, etc.) and have been popping those instead of going the the cupboard or refrigerator. I'm now into my 3rd week without a cigarette and have been playing with only 5 pounds (up or down). I figure I can live with a 5-pound difference. Don't give up on it. Your health will be much better in the long run, even with a few extra pounds. The cravings will subside and you'll still be smoke-free.
