I smoked from the time I was 17 until I was 62. I tried all the patches and gum and it only worked a few days or weeks at the time. When I went for my physical in 1-07 and asked my doctor about Chantix I thought he was going to hug me. I used it and quit and haven't had one since but still love the smell. Sometimes I think I want just one but I know one will lead to a pack to a carton and that would start me again. the only problem I had with Chantix was the strange dreams the first couple of weeks.
