I started Chantix last month, and have been smoke free since Nov. 22--I can't believe it. I had the prescription for over a year before I had the nerve to take it. I am on medications for depression, and the side effect warnings scared me. But guess what, the only side effect that I'm having is stomach problems -- that I can deal with. I never could dream before and now I'm dreaming--I love it. I'm waking up feeling like I slept , which I never used to do. I discovered this website by accident, and I hope it will offer support and others to talk to. It's been tough because of the triggers that remind you it's time to have a cigarette, but I will not smoke again, and it's getting easier--I chew alot of gum. I am an addict. I smoked for over 40 years. I quit one time for 6 years, and started up again because of stress. I know I can't ever have a cigarette again, and that's ok. Has anyone taken Chantix for the full 12 weeks, is it necessary to take it for this long? I was wondering why the makers don't decrease the dosage as you get closer to the end of the 12 weeks.
