There are no so many simple and effective ways to do something or NOT to do. But I must confess Allen Carr's method works perfectly.
BUT there is one condition the method doesn't work without. You must be really eager to drop smoking. I mean it's not just "Everybody says smoking is a bad habit. Should I maybe quit?". Nope, you must be seriously tired of smoking. If you don't feel rejection of smoking or even like it - don't waste your time to read this book, it wount work.
By the way, I had smoked for 15 years, 20-30 cigaretts a day. I read the book. Now I haven't been smoking for 6 years.
