Definitely bring your favorite soap and shampoo. When I could, I would wash my face and hair in the sink until I was allowed to take a shower. It helped having my usual soap, face lotion, and shampoo to feel normal. I also took my ipod and smart phone so I could surf the internet, and when I left the room, I hid them in my sheets. I thought that no one would want to go through my sheets and blankets.
I've had three surgeries and all three times they have made me eat really soon. It was surprisingly soon. One tip--if you feel really sick after eating, tell them. I didn't tell my surgeon that I was sick after my third surgery until I was vomiting the food back up (I was stupid--I kept thinking that if I forced myself to eat, I would be able to leave sooner and see my kids). The site where they reconnected everything was swollen shut and I had an obstruction and an abscess. If I had reported my severe pain and nausea earlier, I probably wouldn't have gotten as incredibly sick as I did. I didn't have any problem healing with my first two surgeries so I thought that if I just gritted my teeth and didn't say anything, it would be mind over matter. Stupid, I know.
