Timely info as I am having a bit of trouble getting all the sleep I feel I need. I would just add that it might be a good idea for some to hang some dark curtains where they sleep. I noticed that as soon as even a tiny bit of daylight hits my eyes in the morning it wakes me up and is hard to go back to sleep. I read somewhere that light, even on the skin will start hormonal reactions get the body energized for the day.
