The Well-Rested Woman, by Janet Kinosian

I have a long, love-hate relationship with sleep and a vivid history of insomnia, so whenever someone writes a book about sleep, I read it. Hasn't made a whole lot of difference, but I like Kinosian's set-up. She presents a wide variety of variables, and possible fixes/treatments. I still have trouble sleeping, but this is the best book about sleeping I've read.
