after 13 days of thinking that champix would not work for me I woke up and could no longer smoke, I tossed my packs to the curb and I'm done with smoking. That said I have been having urges to smoke but they are quite mild and I think they are only habitual. What I am afraid of is that I am a low carber and I have been munching all day on carbs so I guessing I'm in for some weight gain
