I read the book about 2 years ago. I read it in 3 days, but found it more entertaining than helpful. At the time it hadnt come out that alot of it was fictional so I was impressed that he was able to on his own. Loking back though I agree with you if he did stop on his own hwe is a rare case. Ive been trying on my own for years and regret it. After years of never taking NA or AA seriously I now know I made a big mistake. Im still dragging my heels as far as getting to a meeting, but atleast ive finally come to accept that is what I need to do.
I cant reccommend anythinfg else as far as reading material and would also like to hear some recommendations for others, but I do know I wouldnt recommend freys book as a tool for recovery.
