Dry is a memoir by Augusten Burroughs. It's about his struggle with alcohol and drug addiction as a twenty-something. I finished this in 2 days -- I just couldn't put it down. I'm lucky to have never had severe addiction problems in my life, but I could definitely relate to the feelings that he talked about in the book and the irrational thoughts that can come into your head when you're lonely or angry.
If you've ever fought the demon, whether it's booze, crack, or personal productivity websites, check out this book.
