I packed many things I didn't use but the following I found helpful and essential.
Notepad and pen for things that I wanted to ask my doctor but kept forgetting. Also used it to keep track of daily activities, medications and notes to my kids.
Earplugs!! Sure helped get me through the nights (and naps). Eye mask to keep things dark.
Charger, phone and tablet, For news and email/texts to family and friends. Earbuds so I could listen to relaxing soothing music.
Toiletries. Extra facecloths and hand towels.
I wore a hospiral gown the whole time but I had track pants for my legs. I found a shawl worked better than sweater, hoody or dressing gown. The shawl left my arms free for IVs bloodtests etc. Woolly socks and slippers.
My favourite blanket and pillow case.
Books if you read a lot.
Mints to keep my mouth moist.
A small flashlight was useful.
We all had our own rooms in the transplant ward but I always asked them to keep my doir shut.
Sorry for such a long list but these items made everything more endurable.
I had one gentleman on my floor who brought in a special pillow to sit upright with arm rests.
Hopefully this may be helpful.
