I was never a huge smoker, at most I smoked 1/2 a pack a day for about 4 years, but I quit for a few years and what worked was just deciding to one day. Like, not making a big deal about it, and not doing it for anyone else but myself. I was in a situation where my girlfriend was living 300 miles away, I was living with my parents, and no one I knew smoked. It just seemed dumb. I started again a little bit in the last 2 years and I kick myself. I've had one already this year, but maybe I could make it a one-cigarette year. Worth a shot.
Just think about that awesome full lung capacity. Seriously!
And, finally, I'd temporarily avoid watching French New Wave film and anything featuring late-60's, early-70's Rolling Stones.
