If you're doing the cold cap music might be difficult because of the kit that goes on your head. You might be able to wedge an ear bud in.
Magazines, unless you've got a book you're totally engaged in. It can be hard to concentrate, especially the first time.
I was put under a heated blanket called a bear hugger, and my preferred temp for that was 38°! Thick socks, and layered clothing is good.
An tablet with easy shows/movies loaded. Your phone to message friends & family.
And pack a beanie to go home in! There are icicles in your hair when they take the cold cap off, and it took a few hours for my head to warm up!
If you don't mind me asking, what sort of chemo are you having?
All the very best for Monday Trikki. K xox
