Do post a diary. AND, from my experience with hip replacement -- you don't need to take much to the hospital. I don't think I even ever opened my bag. They make you wear their own gown, robe, etc. And I went straight home upon release. DO leave your jewelry at home, even wedding ring. If you do wear it, they'll just make you give it over to whoever accompanies you, along with the clothes you wore in. I just wore the same clothes home (something easy to get on and off, and non-restricting). I think I just wore loose yoga type pants. My doc doesn't send folks to rehab, so I went home. My DIL stayed with me for one night at home, and then I was fine on my own, with her or my grandson coming in and out the first days to help me if I needed it.
You'll be amazed and delighted at how good you actually feel. I woke up clear headed from the anesthesia, and had very good pain control (which does make you a bit fuzzy and sleepy). When they got me out of bed not long after the surgery, I was so surprised and happy and how little pain I had compared to before the surgery that I actually cried!
