i smoked 1 to 2 packs a day for 3 years. i quit cold turkey about 3 mos ago. It took me moving 2000 miles away from home and away from all of my frieds who smoke(not for that reason tho). Its 1000x's easier to do if you arent around it all the time. u kind of have to plan ur day around it if at all possible. If u can make it through the first 1 or 2 weeks its easy after that. i will say though i had some fuckign headaches in the first 2 weeks.
