@gaylea1, While you are still waiting, I will still keep you in my thoughts and especially my prayers.
Inability to sleep was a big problem that I also experienced. And 4 hours sounds like about what I was able to get. Sometimes I napped, but mostly it was a matter of lying still and trying to think positive thoughts.
I also could not lie down, but 'slept' in a propped up position. And I spent much of the night pacing the floor with my labored walk because I hurt so bad. One thing that i enjoyed though was watching night shadows of tree branches that reflected on my ceiling, They would dance as the winter winds blew, and I let my imagination tale over.
One day at a time. Rosemary
