I smoked for nearly 50 yrs. and decided it was time for a makeover. I tried various things, but for me they weren't very successful. Then I tried Chantix. That was what I needed. Haven't had a smoke for nearly 2 yrs. You do need a prescription from the Dr. though. There are many times I wish I had 'just one', but know that it would not happen, so I don't. I'm very proud of myself and w/ the money I saved, I was able to buy a used Viking Designer I. When I look at that machine, I know it was worth it. But try Chantix if you are having problems. Good luck. Marge L.
