I have sleep apnea and find it hard to wake up in the morning and to stay awake the whole day, sometimes i have to take a 3 hour nap at different time on any given day. I recently had another sleep study done and it showed no REM sleep. I was and am still on a apnea machine but the pressure was set to 10 now instead of 6. Maybe you can get another sleep study for sleep apnea? I know how hard it is if i had it my way id sleep the whole 24 hours of the day, and i'm waiting for the 10 pressure to begin working.
