I stayed constipated and bloated causing me to gain 15lbs which was miserable for me since I am petite so I had taken Chantix for 6 mths and stopped. I got a prescription for a weight loss drug which did nothing but speed me up and want a cigarette so therefore I am smoking again. Now 1 year later and back to my original weight I am willing to try Chantix again. Other than taking fiber pills and eating better any suggestions on keeping off the weight and not being constipated all the time?
