I quit in June '01.
Over the summer I sort of picked it up again on a not-so-regular basis but when I got back to school I found myself actually buying packs.
Then I realized that was bad so I stopped and only bummed shit off people when I was drunk. But then I would always wake up feeling like shit because of the cigs so now even when I'm drunk when I get the urge to bum one I tell myself no.
Take it from me, quitting rocks.
