re. mouth ulcers Do whatever works for you. Once it stops working, try something new. I am currently rinsing with a very strong salt water solution three times a day. All my other go-to cures have stopped working. Yes it is tedious but the pain from the ulcers are not worth stopping it.
re. vision I found I needed stronger glasses so just bought the cheapest. I also ended up with sensory sight issues so could not read, watch tele or use the internet for long lengths of time. Screen time was the worst. My vision has since returned to pre treatment. Paclitaxol appeared to be the culprit for me as my current chemo regime has not affected my sight at all.
As you say, we do what we have to do. Sending big hugs
