SLEPT! Not sure how or why, but was it great. I would wake up alittle to change positions, but it was nothing like previously when I was so uncomfortable I would have to get up and ended up back in the recliner. When I did wake to shift all I would think is wow, how much I wasn't uncomfortable or hurting. It really was the most wonderful sensation, my knees just were. I have no idea if it will happen again tonight or not, but like many of you have said, it shows the light at the end of the tunnel.
