This is totally perimenopause or menopausal.
What helps me?
If I wake up and I don’t back fall asleep in 10 minutes, I read a book until I feel sleepy again. Usually about 30 minutes later. I do not look at screens though.
No afternoon caffeine. I even find that iced tea at lunch or any kind of caffeine in the afternoon will mess me up.
Try to take at least a 20 minute walk every day if I can. (especially on the days when I’m not really exercising; I go to a one hour exercise class three days a week)
I am on an estrogen patch, and the prescribed progesterone with it really helps
