Wow! When I sit down at my computer, I always want to smoke, even when I play computer games. The cigarette may burn to the end without my puffing on it more than once or twice, but I seem to want it in my hand. That being said, you've made a good choice to replace one behavior with another one. I also have not told people I'm quitting. I know you're supposed to, but that makes me so worried about failing that I'm inclined to smoke.
