I gave up sometime around June last year. I attempted it many times before and believed I had succeeded after a month or so. Because I was always thinking about the timescales for withdrawal and forgetting the psychological side if things, I then considered myself a non-smoker. This in turn would always lead me to starting smoking again because I believed I could just drop it when I wanted.
I then tried little niquitin minis for a few months and was doing quite well. As a reward for doing so well, I then started to smoke just a weekends. That then became weekends and lunch, which in turn became weekends, lunch, breakfast and dinner...
Soon I realised, using my savant like intelligence, that 5-10 fags a day means I haven't given up yet. Within 24 hours of this incredible piece of deduction, I bought Allen Carr's book in a fit of fear that I would smoke for the rest of my life.
Over the course of the following few days, I spent every spare second reading his book and never smoked again. I had no issues, no withdrawal and I'd be very, very surprised if I ever smoke or feel good about smoking again. It's not a magic bullet, I know many who've read it (or say they have) and have remained smokers.
Perhaps it was because I truly wanted to give up and was motivated to finally kick it, but I found the book was so much more than a major crutch and guide. It provided me with a lot of extra motivation, mainly through giving me an anger towards smoking and the industry in general. This enabled me to feel like I'm not just doing myself good, but sticking my fingers up at the Tobacco industry by not paying them to provide me with a means of inhaling some burning old leaves to aid my death.
I finally succeeded using Champix which are the tablets you get from the doctors.
Aren't they supposed to give you hellish sleep, mainly through nightmares and bizarre dreams?
