I've read the book and it made a lot of sense to me, but I've read a lot of other recovery books that also made a lot of sense to me. The only thing that turned me off of RR is the for profit motivation behind it. I guess there is nothing really wrong with making a buck off it though. The recovery "industry" is a multi-billion dollar business now.
Personally I've never smoked crack. My understanding is that while not "physically" addictive, it is extremely mentally addictive. IMHO the mental addiciton is the tougher of the two anyway. My DOC was pot and my addiction to it cost me pretty much everything. Never ended up on the streets, but that is only because I had family to fall back on. Lost my marraige, house, job, went bankrupt, stints in the mental ward & rehab, suicide attempts, went through it all. I've been clean for about 10 months now. I'm not really sure what made this attempt to stay clean different from the hundereds of others. I did have something to gain from staying clean, a chance to rebuild a relationship with my son, but I had thrown that opportunity away before just to get high. Though it sounds cliche, I just had to finally reach the point where I wanted to stop for me. The point that I started caring enough about myself to quit and stay quit.
I've been on these boards for years and have gotten alot of support and knowledge here. I found it necessary to "study" the various methods of recovery and use bits and pieces of all of them to stay clean. I wouldn't necessarily recommend this approach, as it took me about 7 years from the time that I actually started trying to where I am now.
I didn't have a "spiritual awakening" or anything like that. One day I just decided I couldn't continue to live like this and really comitted to it. It was years after all the really bad stuff had happened. While I generally consider myself to be agnostic, I have come to have some kind of understanding of god in my life, but I don't find that to be in anyway a part of staying clean. Probably the most helpful tool I have found in all the recovery "research" I have done it the Cost/Benifit Analysis. It makes a lot of sense to me and I can see and touch it.
