I’ve had it for over a year. I have wondered why and suspect post covid syndrome. I’ve tried various things, but nothing helped that much. It has improved on it’s own, but I still wake up between 2-4. Now, I can usually return to sleep. Plus, I go to sleep early between 8-9 p.m. so, I normally get 6 hours before I wake up now. I’d like to sleep from 11 a.m. to 7 a.m.
