Cindy16 I didn't take the Chantix for the full twelve weeks. I had planned on doing it, but there were mornings when I didn't eat early so I ened up skipping that pill. Then there were evenings when we ate dinner so late that I ended up skipping that pill, etc. So I just figured the heck with it! I feel really good about it though. I still get cravings - about once a day- but they pass. It's more of a habit craving now. I think "I should have a cigarette now". Then I think "No, I quit smoking". It is very manageable now. I just can't believe how I let something get a grip on me like that! So have a great smokefree day!
