I appreciate that most people are understandably skeptical of anonymous online reviews. If you're one of those, Google this book and find the video clips of credible and/or celebrity folks giving a ringing endorsement. Here's mine.
I have literally not had a single cigarette since I read this book. In fact, as I started to read it, I told myself that I would finish the pack I had just bought and then try to stop smoking for a week or so. Then, as I neared the end of the book, I threw the pack away. I was literally anxious to become a non-smoker. I know that sounds overly dramatic, but it's the absolute truth (and why I was moved to write a review). The six dollars I spent on this book was very probably the best money I've ever spent.
Frankly, as I type this, I wish I were a better writer. I wish that I could figure out how to convey absolute endorsement of this book without sounding grand or generic or like every other advertisement.
Here is the best endorsement I can muster: This book is one of my most prized possessions. If you want to become a non-smoker, buy it right now.
