I smoked for 40+ years. I tried to quit a few times during that period by going cold turkey. I always returned to smoking. My doctor finally told me I HAD to quit after showing me my chest xray. I drove to the nearest drug store and bought a disposable electronic cigarette. I knew with the first puff that I could stop smoking cigarettes and replace them with e cigs. I ordered an e cig kit online and when it came in the mail, I stopped using cigarettes and have not smoked one since. That was 20 months ago. I no longer desire a cigarette at all. My husband is happy I no longer smoke and supports me whole heartedly in using e cigs. I smell better, too. I use liquid with low (9 mg) nicotine and 0 nicotine. I am finding I need/want nicotine less and less. I mainly enjoy the mechanics/motions of smoking, rather than needing or wanting nicotine.
