I think that depends on the person. I used Chantix and it was very easy to stop smoking. The hard part was not picking it back up again. For weeks I had to fight habits: I needed something in my hand, I felt 'hungry' no matter how full I was (after eating smoke), I was watching a movie, etc. After a couple of months the majority of the triggers are gone but occasionally I still find one. When that happens it isn't as hard because I broke so many of the other habits I know it will pass. OTOH I enjoyed smoking, but I had to quit because I can't afford it and my other half is an ex-smoker.
