@Fernweh I found chuppa chups where life for the metal mouth. I’d be sucking them all day everyday :) (the mini ones in the tubes of 25 for $7 from big w were my thing!)
and rinsing my mouth minimum three times a day with the bicarb to help prevent mouth ulcers.
I found that for 48 hours post chemo I completely craved carbs (hot chip sandwiches became my staple ha ha ha) and then it would flip over.
I found I was tired all the time too- but decided that was chemo life and is just be kind to myself and not try to do too much.
Speak with your medical team. I got worded up very quickly to talk to the team about every effect I was having as there was “something for it” and they were as good as their word. Even when the reflux got bad they just gave me more and more stuff to help out. I can’t fault them. If I spoke up, they totally actioned it. So I’ll encourage you the same.
Hang in there.
