One trick that worked for me (pack+ a day smoker for 5+ years) was not exactly calling it "quitting". I had tried quitting a bunch of times, but every time I had a lapse in will power and had a cigarette, the justification to start again basically went "oh well, guess I failed quitting, time to go out and buy a pack." When I changed my mindset to more of a "I just don't really smoke anymore." it was ok to have one every once in a while when I was out with friends and not feel like I failed. Now I'm basically down to only one cigarette a year or two when I'm with old friends, and I usually feel bad enough in the morning after it that I don't really have any desire to smoke again for a long time.
