Started stealing my dad's cigarettes around 14, was buying packs at 15, smoking a pack+ per day by 17. Somewhere over the next 35 years it went to two packs+, and was probably at that level for at least 2 decades before my final quit on 11/7/01 at age 52. Like most I had "quit" several times before, but never went more than a day or two completely without smokes. The last time was so relatively easy that it scared me for a while (as in, this can't be really happening, it's just going too smoothly). I still have occasional dreams that I smoke a cigarette and trash all this smoke-free time, but when I awake I know instantly it's just a trick. My sincere best wishes to anyone making a serious effort to quit. I still believe I enjoyed it, but I know it is unhealthy and I got really tired of hacking and coughing to start each day. I have had perhaps two colds and no respiratory infections since quitting. Before that I was good for at least 2-3 colds a year and at least one respiratory infection/inflammation that would require treatment each year.
