Wow! I'm two days behind you and can't imagine walking that far. And with a cane, no less!
I've also done well sleeping. Husband and I switched sides of the bed and can manage. I think it's important to try.
Interesting, both my surgeon, and the visiting nurse said take your full strength narcotics at night to help you sleep. Even skip them during the day, if you don't need them, but take them at night.
