I'm only giving this book 5 stars because it worked lol. It used a lot of the same methods I used last time I quit smoking for a stretch of 1.5 years. This time I feel it will be for good. It was terribly written with a lot of YOU CAN DO IT sort of nonsense in caps literally, but it worked. The brainwash really worked for the better. Honestly would read it again if I ever have the urge-and honestly the thought/threat of having to re-read it is almost enough to prevent me from trying another cig again.
