I found his book Recovery to tell a very powerful story of his trouble with addiction, and how he has worked through it. He goes quite deeply into self introspection and analysis of himself and his character, and how he needs to remain constantly vigilant of the instincts and urges that took him down those paths to addiction many times before.
I found this book to be one of the most raw and honest things that I have ever read. I'd really recommend against discarding it because of not liking the man or his character.
