Yup. It's not easy.
It is 16:42 here. I just got back from the range. This is the first time today the thought of a cigarette flew through my head. Each day I get farther and farther away from the hook. I quit on Ground Hog Day.
Each cigarette reinforces the urge to smoke another cigarette. The only way to lose the craving for cigarettes is to stop smoking. It's a bitch, but there it is.
