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.
