Really enjoyed reading this - thank you!  Sleep is a strange thing.   I now go to bed when I feel sleepy, which can be as late as three or four in the morning, and frequently get only four or five hours sleep a night.  When I was working I would stress about getting seven or eight hours sleep a night and would fret when I didn't.  Now that I am not working, I don't stress about it.  I figure I will fall asleep when my body and brain need it.  Years ago I was reading a book titled The Private Capital.  Could not get through more than two pages without falling sound asleep.  That book was better than any sleep aid on the market.  Again, thanks for sharing your story!
