I did take a walk this AM to see if the sun would wake me up, but I still fell asleep teaching Math. (So did my student!) Of course, I had been up since 3:30 am, so I had a right to be tired, LOL. I'm going to try Meta's suggestion about earlier meds and your suggestion about sunlight in the mornings and see if that makes any difference.

Thanks, gang. I'll let you know how it goes.
