My mother has recently finished chemo.
We weren’t allowed to sit in with her due to lack of space so one of us would drop her in the morning and one of us would collect her after the treatment ended. During the first treatment the nurse was able to give her an idea of how long she had left so she could text in good time for us to be waiting for her.
As above plenty of food and drinks available but the Chemo team advised if she wanted something particular (a brand of tea for example) to bring some with her.
My mother had a bag of stuff, so iPad, phone, charger, headphones, knitting (😅), Netflix app loaded, audiobooks etc.
Cosy blanket, thick fluffy socks, lip palm, hand cream, bag of sweets, just things to make the time a bit easier.
If you aren’t already a member consider joining a library so you can use their digital services - BorrowBox is brilliant. My mother found it difficult to read as she had quite bad brain fog (but she’d had an intense log radiotherapy treatment before Chemo) but audio books were manageable.
There were often charities/organisations visiting during different times. The Scarf Ladies for example who gave lessons on various ways to tie headscarves.
Look up Maggie’s organisation as well - they are fabulous. I wish we’d known about them at the time.
Good luck with your treatment.
