Walk around a lot after surgery. Learn as much as you can about caring for your ostomy from the nurses while you're there in the hospital. One thing I found exremely helpful was having a home care nurse come to my house for a few visits after I got home. Check with your insurance company. I think I was covered for five visits. Take one day at a time and you'll be fine.....good luck! 

Good luck! Will be praying for you. I had mine done in one step ten years ago so I don't have advice specific to your surgery tomorrow. BUT- I did just have adhesion removal a few weeks ago and definitely walk around as much as you can...helps with the gas. Also, make sure they ween you off the pain pump sooner rather than later and get you on oral pain meds. This last time they kept me on the pain pump until the day before I left and I had horrible withdrawal symptoms when I got home. Just another thing to deal with on top of everything else that could have been avoided! Also, ask for advice on diet for once you get home! I was given no direction and had to figure it out for myself.
