Yes, I found I was also waking early and then with my mind endlessly processing ,I couldn't get back to sleep.This was a problem as I am full time chemistry teacher ( and carer).
Cured myself by accident when I decided that this term I would go into work an hour earlier ,I set alarm for 5.50am, i make myself get up, don't allow myself any nap during day and am falling asleep as soon as head reaches pillow at 11pm.
A side benefit is that I now get a lot of my school preparation and marking done before I get home !!
