More Sleep Observations

Last night I went to bed early (for me) and didn't take the over-the-counter sleep aid I've been taking with varying success for several years. I was afraid to stop taking it...what if that was an improvement over not taking it? But I went to bed at what I thought was a reasonable time and didn't take the otc sleep aid...and I went to sleep:) I am very pleased with the audio book. It refers to things in the book to read if I want to know more about something.  I don't have the book and thought about getting it but honestly, what I want to do is go to sleep not know more about it so I don't plan to buy the book.
