I am a Chantix user also. I have quit previously using other methods as well. I don't think it is Chantix you are necessarily observing. People respond differently to the whole quit process...
Personally, I have had my 'moments' during this quit, but truthfully, they are fewer than other methods I have tried in the past by far.
