@zachary777 , i don’t have any advice, but I think the sleep specialist might be a good resource. It’s unfortunate the endo has no advice. Maybe, a second opinion?

I know that once a certain sleep pattern gets established, it’s difficult to break. I recall back during a particularly hectic year in college I was staying awake a lot studying for exams. I had also worked parttime. After my last exam, I crawled in bed and slept almost constantly for over a week. I got up at 8 and got breakfast, fell asleep on the couch by 10, slept until 6 when my fiance got home, had dinner, then went to bed by 9. Slept til 8, repeat…… It was a struggle to get out of that routine.

I’ll also add that checking for vitamin deficiencies, especially B12, might be good. Also, exercise gives me more energy so working out is important. Good luck with everything!
