I quit. Basically tapered off cigs until my pack ran out. Although the ones I was smoking are insanely strong filterless cigarettes my girlfriends family brought back from ukraine. One or two of those a day was PLENTY to get your fix. It probably also helps I started smoking (well, actually vaping) weed more.
Towards the end of the school year, I decided to quit, did for a few weeks, then had the occasional cigarette socially. Then while waiting in traffic court (for 5 hours) was informed by this chick I was talking to to kill time that camel turkish golds (my favorites) were $6 a pack at a certain gas station, and offered one. That started me up again for a bit.
