Hi there,
I took an an Alexa in with me as the hospital had free wifi, which kept me company during the day, and sometimes during the night when I could not sleep. I suffered a lot from Mucosytis, but as I had my own fridge, I had ice pops and ice cream which were great at soothing it.
If you do get Mucosytis, avoid anything acidic as it will probably be very painful in your mouth.
If you have free wifi, take a laptop or a tablet in with you so that you can while away the hours browsing, or connecting with family on Zoom etc.
Regards, Tony
