Hi Sonja,
I use pillows to keep me on my back. I've described this elsewhere on the forum - I have a thin feather pillow and I push the feathers to the sides so it's flat in the middle. The flat bit goes under my neck and the plump sections either side of my head/face which helps to keep my head from rolling to one side. Then I have pillows under my knees. That pretty much keeps me on my back.
I didn't have to do this over the last three weeks on prednisone but I'll be back to this tonight along with pain meds before I go to bed.
