Oh, I forgot to add that I was only on Chantix for about a month before I was down to 5 cigs a day and decided that I was done! The great thing about Chantix is that you keep smoking while you are on it, so you don't have that "quit date" looming over your head. Your brain will tell you when it's time to not pick up another cig.
Don't worry. I was banded on Friday and I cheated bad on my pre-banding diet. I ate at all the restaraunts that I loved. As long as you at least try, that is what matters. You won't be able to cheat after the surgery without felling like you are being hugged around your mid-section by an elephant's trunk!
