Here are some of the things that I brought to the hospital with me.
Burt's bee chap stick - your might get very dry lips from being under
toothbrush and tooth paste - when it was time to go home it felt really nice to brush my teeth
a pillow for the car ride home - you are going to have incisions on your stomach so put a pillow between the belt and you in the car so it's not so tight and doesn't hurt you. also lower you seat back some it will help as sitting straight up will hurt some
comfortable cloths - I wore very loose fitting close and I made sure I washed them the night before so they were clean
kleenex, plastic bags, and bottles of Water - this is for the car ride home in case you throw up - very useful!
Any medications that you are currently on, also if your surgeron gave you your meds for after surgery before your surgery make sure you bring those for the ride home
i also brough stuff to take a shower, it was more like a wipe down but it felt good after being all hooked up and out of it.
any books or laptops, blankets, and pillows for whoever will be with you.
For the first week I slept in a recliner because of how you can position it. the bed hurt way too much for me to lay down and even sit up with all the incisions.
ALSO MAKE SURE THE NURSES GIVE YOU DRESSING CHANGING STUFF BEFORE YOU LEAVE!!
Hope this has helped some.
