I stayed overnight at the hospital and the nurse said I had to sleep at least on all 30degree incline. Once I came home I slept propped up on pillows for a couple days and slowly worked up to sleeping on my side. I'm a tummy sleeper....I'm 3 weeks out and still not really sleeping on my tummy. Good luck!
Also the pain meds helped with sleeping. I didn't feel a ton of discomfort.
