I think it's the same book... I read how to control drinking, he explicity states that the title is a 'bait' to lure people into the book. Within the book itself he 100% advocates abstinence.
I wasn't a huge fan of the 'don't stop drinking until you finish the book' instruction as I'd already stopped, but I could see the benefit to reading the book whilst simultaneously feeling the after effects of the night before.
