Query: Not worth the paper it's printed on

Wow. In looking for a solution to our sleep problems, I found this book. There are a lot of sleep "training" books out there, and a lot of different styles, but this guy basically comes right out and says you're an idiot if you don't do what he says! How modest!I've never really had the urge to punch someone like I do with him.Didn't finish, needless to say!
