Joraemi, when I went thru chemo, this is what I had in my bag: bottled water, books(both reading & puzzle), hard candy, magazines, and this little blanket-thing that my aunt brought with us while I was there(to put on the chair back--I have OCD). And a hat that covers your head & neck(or a hoodie), I know I was REALLY self-conscious about being bald.
She should start eating potato chips on her good days(when she's not nauseous), just in case her potassium levels drop. That's what happened to me(only I had to go BACK to the chemo place to get the potassium).
If you need any hints, tips, or suggestions--just PM me!
