Bionic, You Cassidy and I are almost triplets--virtually the same age, and all had surgery within 5 days.
As for the sleep problem, I had the same. I was averaging maybe 4 to 5 hours sleep at night for the for about the first 11 days, but never napped during the day. I crashed day 12, could barely carry on a civil conversation. Now I am doing much better, but I'm not sure if that's the natural adjustment, or because I started taking a bit of gravol at night before bed (or both). They are anti-nausea tablets, and you don't need a prescription for them here in BC. I started with two tablets ( 100mg) for the first couple of nights, then went down to one 50 mg tablet. I got a full seven hours of sleep last night, my best night yet. Feeling great today.
Now I don't know if such an approach to enhancing sleep would be recommended on the BoneSmart forum, so hopefully one of the moderators will weigh in. I would recommend listening to BoneSmart over me because this is all new to me. Plus you never know about the placebo effect. I should add the only tablets I am on now (besides 1 Gravol at night) is baby aspirin twice a day, Vitamin D, and Senecot.
I'd like to add that one thing that has really helped me adjust to sleeping on my back is having a deep squishy soft bed to sink deeply into--with pillows for legs, neck and head, so you are curled ever ever so slightly. Normal beds don't allow this. Our bed has a firm mattress, and I can't imagine getting a wink of sleep there. In my case, my bed is the living room sofa. I went to the sofa--on a whim-- directly after I got home from the hospital, and realized at once it was perfect. On the sofa I use four pillows at this stage. Plus I have a fan blowing on me, cooling in this hot weather, and often an ice pack. I almost prefer sleeping on my back now, and there is an added cosmetic bonus--no longer do I wake up in the morning with a puffy swollen face and eyes (orbital edema) which I think was caused by my face buried deep in pillows, plus heat. Several people have told me in the past few days that I look great, years younger. I can see the difference myself.
