Ok, so this has been asked loads of times before, but never mind!
For Sunderland in particular: (because I know the ward!)
nightwear and knickers (plenty - I had stress incontinence when vomiting and the aneasthetic can make you a bit sicky), slippers, flip-flops (I used mine in the wet-room! dressing gown, cardigan or something similar (it can be cold sometimes)
Hair brush, comb, straighteners, dryer, hair products, etc. (I don't travel light!)
Sanitary towels (you will probabaly have a TOTM even if you're not due, the surgery seems to do that to us girls)
toiletries - soap/face-wash, shower gel, shampoo+conditioner, deoderant, perfume (told you I don't travel light !

), face cream, make-up? (if you can be bothered), flannels.
Little portable mirror. There are hardly any mirrors in the ward!
Towels.
dry mouth spray for post-op (Boots), tissues, magazines, puzzle books, ipod. Mobile phone and charger. Money to buy TV card. ?ear pugs (you could be in with a snorer!)
NAS squash or NAS flavoured water - the water tastes foul. Your own teabags if you have a preference.
?Eye mask. The ward lights can be bright even at night and an eye mask may hep you sleep!
Loose clothing for going home in, a pillow to hold against your tum when travelling home. (to protect your wounds)
a small donkey to carry it all!
