RiPHRaPH said "you don't have to cold turkey it. if you smoke 2 packs/day that is 40 cig's. every week smoke one less cig. and in 40 weeks (a small time in the larger scheme of things) you are done."

I'll agree with that, but you do have to eventually quit. I really think my smoking had ended up being more of a lifestyle than an addiction. Then, once I had no choice to change my lifestyle, it really was easy to quit. I really feel that I should try to convince people to quit smoking, but from my own experience, most smokers know that it is bad for them, and they just have to come to your own decision and then just do it!
