I never smoked, but I wanted to understand the psychology of smoking, as I heard it was more addictive than heroin. So I read a book called "Kicking It, the New Way to Stop Smoking Permanently" by Dr. David L. Geisinger, 1978, Signet books (paperback). Great book! Shows you all the tricks the tobacco companies have used, and the habits you picked up, like flicking your ashes, playing with the lighter, etc. It was interesting to note that folks often set a quit date, and then go off to have their last cigarette, puffing away to "enjoy" what should be their last smoke. Wrong! The book exposes the flaw behind this quitting strategy in that your memory of your last cigarette is a pleasurable one. The book sets you up with a program where first you reduce the number of cigarettes gradually, switching to different brands, and even brands you don't like. Then, on the last day, the book has you puff away on three cigarettes in quick succession, inhaling deeply and looking at yourself in the mirror, so you won't be left with a pleasurable memory of your last cigarette. There's a lot more to it than that, but that will give you an idea of what its about. I can tell you that I can notice when a smoker gets on the elevator at work immediately - the stink surrounds them. As a fitness buff, I am sure that smoking does you no favors when it comes to enhancing your fitness level or boosting your energy. Good luck on quitting for good, and welcome to the world of non-smokers. Quitting smoking is one of the best things you can do for yourself.
