I too struggle with fatigue. I cant go to sleep when I go to bed, and if I stay in bed trying my back starts hurting and I have to get back up. When I do manage to fall asleep I'll wake back up after a few hours, or my back will hurt too bad from being in bed. Last night (early this morning) my fatigue was so bad I was holding my breathe, and trying not to cry. I had went manic a few nights earlier and sleep was escaping me. I took as much sedatives as I could find, that I thought I could safely take?? And laid in bed trying to relax. I woke up a few hours later feeling a little better, but my fatigue is building again.
