I haven't slept well since the surgery because my knee couldn't find a comfortable position. I did sleep in fits and jerks during the night, but I've napped, too. That, too, wasn't especially comfortable until this afternoon. This afternoon my knee was enough improved that the slight sideways pressure of sleeping on my side didn't hurt. I had a wonderful nap. I don't know if I've ever napped three days in a row before. If so, it was so long ago that I don't remember it.
