My blood pressure tends to be on the low end. I would say my average is 110/72. Maybe it drops too low. That is a good point. It mostly happens in the evening. I will mention that when my pdoc returns my message.

It doesn't resolve itself when I lay down but when I wake up 12 hours later it usually is. I looked up the symptoms of hypotension and when these hit I can barely think much less concentrate and I always have fatigue but these give me an overwhelming desire to sleep.

Thank you for you input, it was very useful.
