I had trouble quitting cigs. chantix, patch, weaning, cold turkey. I just couldn't do it. Then I discovered the e-cig, worked like a charm. Haven't had a real cig since May 2010. After a few weeks I could climb stairs and exercise comfortably. I could breath again! I know quitting is better but I didn't have the willpower. If your having trouble quitting maybe give e-cigs a try.
