I read this just having read Beautiful Boy by the father of Nic Sheff. It exposed a few things that the father left out (or maybe doesn't realize) about Nic's childhood that maybe led to his addictions. But this book was kind of rambling and conversational in a bad way (lots of "you know?" endings to sentences. No, I don't know.) Interesting concept - very marketable - but I liked Piece of Cake better as an addiction/redemption story.
