Is she taking L glutamine? Here's a link to a study out of Dana Farber:

I'm in my 3rd week of taking it (started week 6 currently finished week 9) and I've had very mild neuropathy that lasts about 1-2 days per cycle and not even all day - very transient. She needs to make sure it is high grade / pure (which can get expensive).
Also, a B complex vitamin with high doses of B-6 and B12 also taken daily helps as well. Good luck to her!
