Hi
@hippywoman! I hope that I can bring some relief to your sleeping dilemma. If you go to page 13 of my thread, you will see a rather comical photo of me in my nest. And my posts on page 14, #261 and #271, describes what is under those covers. I think I counted a total of 7 or 8 pillows at one point, not counting the wedge. Shortly after the photo was taken, I took away that big, fluffy arm rest cushion, because it just started to get in the way. Now, bear in mind that I was using our guest room bed and it has a memory foam mattress on it. I chose to use this bedroom since it was not only closer to the bathroom I would be using, but enabled my hubby and me to get restful sleeps, without worrying about disturbing each other.
I was also a side sleeper and found this to be so comfortable, that I still use this method. I have, however, just recently tried sleeping on my side, with one pillow, lengthwise, over my right (non op) leg, which is bent. Then I put one pillow at the foot of the bed, for my op side foot to rest on, and then another between my legs, up close to my crotch. There are also a couple of pillows behind me, for back support. But, I actually find myself rolling back onto my back, now, since it is so comfortable for me. Yeah...I know....an enormous amount of pillows and if you have to share a bed...forget it...unless you have a king size bed!
But, bottom line is, it is a trial and error situation finding your sweet spot. I hope some of this benefits you and you can finally get the sleep you need. Best of luck to you!
