I am using Chantix for the 4th time in over 10 years. The second time I used it I quit smoking for over 2 1/2 years. It worked beautifully for me: smoking provided zero pleasure and it was easy for me to quit. Since then I have found Chantix to be less efficacious. I'm nearly finished with the second week and I can still get a slight dopamine hit from a couple drags. Is there such a thing as Chantix resistance? Has anyone tried three doses per day instead of the prescribed two? I didn't find anything useful on the internet.
I'm a 40+ year smoker.
