Welcome,
I had 4 treatments of carbo/taxol and I have to say I didn't do too bad. As far as permanent side effects my bones tend to get achy, especially in the hip area and lower back but it's a small price to pay.
As for Avistan, I have no knowledge.
Keeping notes is great advice, I can't tell you how many times I went back to my notes to see what a particular doctor had told me.
As long as your mother is able to be independent and wants to be, bless her heart, I agree with you to let her.
