Hey, I was a day case too and tried not to take too much with me. A phone charger is good, and a zip up hoody to travel home in. I also took a travel bottle, one of those ones with a straw attached so I didn’t need to lift my arm to drink, that was handy for recovery too.
One thing I didn’t take that I needed though was a dressing gown and slippers. They can give you theirs but she said I could have worn my own which would have been comfier!
I didn’t need throat sweets, extra clothes etc. The less you take the less you have to worry about bringing home
