I've been there unfortunately and have seen the best specialist in the country. Exact 2.5hrs sleep or even zero in 48hr and totally wide awake. Sleep psychologist said the best thing to do is not remain in bed.
So it frequent I live your schedule and am up doing things if not asleep. It was determined all medication be stopped. I know how you feel and can emphasize there is no other Western medicine that can help me.
Sorry to hear you are experiencing similar.
Take care,
Alan
