I smoked for over 50 years when I was diagnosed with COPD. I tried Chantix but ended up going back to smoking after a few months. My doctor recommended I try Varenicline 1mg. I believe it is generic chantix. You can smoke until it starts working and It took about 3 days to kick in and I haven't had many yearnings. When I do have one I take an extra 1mg tablet and the urge to smoke fades away in about 20 minutes. Tell her all us former smokers find it difficult to quit but we need to just bite the bullet and keep trying.

Tina, my sister, a smoker of 40+ years was able to quit by going to a hypnotist. It was the only thing that ever worked for her after so many failed attempts.
