That didn't go too well

First night of trying to sleep (emphasis on trying) with the scaffold (high thigh to ankle brace) on my leg.  I don't sleep well on my back, but am being forced to.  If I had a reclining chair, that would work, but we don't have one. I stack pillows so I am sleeping sitting up, but on an angle. Mixed results. Hoping it will work tonight due to sheer exhaustion from not sleeping worth a damn last night.
