I quit that way. I made a decision to stop smoking and switched to using a vaporizer. That satisfied the oral fixation and I felt better, physically, rather quickly. I then tapered off the nicotine (pretty quickly, compared to most people). Within a few months I was using zero nicotine mixes. After that, the next step was to limit it to home and bars, still with no nicotine. That was seven or eight years ago. I've had two cigarettes since and both tasted abysmal. No interest any more. My vaporizer hasn't left my desk in years. Occasionally I'll puff on it when I'm really stressed but it's a placebo and a habit of over decade of smoking. Changing rituals and eventually getting rid of all the nicotine was my path to success.
