I'm still on puree and I'm struggling to get protein also. I only had nausea with yogurt and I just haven't eaten it again. I tried to sneak it in other foods and I didn't feel as bad. It's hard to find good foods. I have a ton of half eaten things in my fridge that I'm slowly circling back too
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.
