Heya Poddy best of luck for ya op,
if you really wanna have some fun whilst in hospital try this, I did it when I was in hosp last year for a lung collapse...
Get hold of an empty saline drip bag, ask the nurse to remove the pointy bits(needle) get a friend to bring you in a black coffee(or use the coffee they serve you with food(not worth drinking) and use a examination glove, nick a hole in it and refill the saline bag iwth coffee. Tie off the end and put the new "mainline coffee bag" up on the drip holder next to your bed and get the nurse to tape it to the top of your wrist.
Then when your surgeon does his daily rounds the look on their face is sooo worth the effort "i didnt like the coffee doc so I mainlined a batch a friend made"
Seriously its worth the effort!
I made my own fun in hospital...
Hope it goes well for you..
