I smoked for 6 years, the ast two years almost a pack a day. I got a bad chest cold and didnt smoke for a few weeks cause it hurt so bad. After I got better I realized that I didnt need them, so I started eating fireballs and jaw brakers like it was my job. After not smoking all week and smoing two pack in 4 hours at the bar on a saturday noght I eventually quit all together. Im also a hypocondriac so evey sore throat or headache is cancer or a tumor so that helped.
