I have heard very good things about Chantix
I tried Chantix, but in all honesty, I did not give it my best effort.
My place of employment instituted a smoke free policy on Nov 15. I can only smoke if I leave the property at lunch time.
Now, being forced to quit/cut down just makes me angry and is very counter productive to quitting. I have to WANT to do it or it's not going to work.
Side effects I experienced with chantix...
Gas -
, nasea if I didn't eat before taking it, and FUNKY UNPLEASANT DREAMS.
I will try it again soon, when I can get past the politics of being told what to do by "the man".
