Most hospitals have a pay for tv service....very expensive, so don't have WiFi....download lots of BBC programmes on laptop or tablet to watch without WiFi....or portable DVD machine....iPod or mp 3 for music...Good books....ear plugs, eye mask, wet wipes, mirror , cosmetics so you feel human...bit of perfume....dishy doctor......
Take Tea Tree Oil, Eccles....wipe everything with it......don't let anyone near you unless you know for sure they have washed their hands...insist that consultants take off their outdoor coats before examining you....I know one who did rounds in a flowing waxed coat....P....... the Pillock he was known as....
Pay a child to sneak you in edible food......should they object form your own religion with special dietary requirements......
If you are going to be pretty poorly for any of your recovery time, make sure you have someone to visit you regularly who will speak up if you are not being looked after properly.
You will probably be told you can't bring in your mobile phone, but staff are obliged to do this as the private PFI companies who run the hospitals want you to use their expensive TV/phone/Wifi services.
As long as you are reasonably discreet the ward staff don't mind. I found the new smart phone I bought before going in a great help.
All the books came home unread. There is so much going on that you may not be as bored as you think.
