I have mixed feelings about this book. I finished reading it and it makes you want to change many of your sleep habits, but at the same time I felt he may have overemphasized certain "facts." If you believe everything word for word it is scary...thus my mixed feelings. But incorporating many of his ideas are without a doubt a good thing.
