That is me too, sleep for an hour, up, do some laps around the house, look like a caged lion. Read, fall asleep, wake up read the same page 20 times. Dream in between, weird dreams. Try to go to bed, can't sleep, move to sofa, can't sleep, back to bed. Walk some more, get on computer sometimes, watch tv, can't take much more HGTV and and Used to love it, same with the food channel. Finally find an old movie that seems good, fall asleep long enough to not know what the heck is going on. Knee is so stiff, so restless, then pain, then over and over and over.
Thing is I just went through this in January and it does end. Honestly it does. Hang in there and just go with it. First time around I was very pouty and crying, that is how I found this forum, this time around I feel better about it. I just sleep when sleep finds me. Here's to a few good hours.
