Im with there today, Im going on 5 hrs of sleep over past two days, 12 hr working shifts inbetween and another 12 hr shift in the morning and its 3am and Im to be up by 7am. I fell asleep once tonight but was dreaming so "real" that something big was bitting my arm, at which it woke me up to realize I was digging at my arm. nothing there but the lesion I had created by digging. I agree with the others that say pressure to sleep surely creates difficulty in sleeping, I remember saying to myself I have to get some sleep tonight. Of which I did get 2 hrs. hope that counts for something in the morning. Well off to try again...good luck and sweet dreams to you. PS: maybe if I hung something over my bed to look at it would help? Ummm just thought of that.
