"The Courage to Change" by Dennis Wholey is a pretty good read. It has first hand accounts of how different people fell into alcohol abuse and how they dealt with it. Included are Pete Townshend, Doc Severinson, Graham Chapman, Sid Caesar, among many others. They all have their own chapters, so you can just pick it up from anywhere in the book and read about a particular person's struggle.
"Dry" by Augusten Burroughs is another pretty good read, but it's more linear. Being a narrative it does get bogged down with all the other things that make up a marketable book: love story, friendships, work, blah blah blah.
Happy reading and best wishes!
