This is the best way that I've found to stop smoking, and I've tried just about everything. It's all psychological, which is good as doesn't involve any horrible patches or gum that burns your mouth, and it actually tells you how to deal with cravings. The only problem I see is that the book is £6, and the game is £12, and they're both the same thing, something I didn't know until after I'd bought it, but if I'm being honest, I don't care how much I paid, I am officially a non-smoker!
I played this game over a two-day period, and had my last cigarette that night. The next morning, I looked at my packet, realised how disgusting it is, and broke them all up, and I've been smoking for 8 years.
I highly recommend buying this, even if you were like me and didn't really want to stop, but thought you should for whatever reason. It's brilliant, and it works. What more do you want?
