My heart goes out to both you and GE.  As you may recall, I've been performing as care-giver for a dear friend going through Chemo.  It's been an unexpected challenge.  She's almost done - had her last treatment, but we almost lost her two times (she had to get a transfusion).

Two things to be aware of from my experience (that you might already KNOW, but if you don't....):

1) The first treatment is the worst, because they pretty much max the person out based purely on body weight.  They don't know how they're going to react, because everyone reacts differently.  So keep a real close eye after each of the initial treatments, as they adjust - they're groping for the right treeatnment/amount.

2) "Chemo-Brain".  The person you're caring for will say and do really stupid things, sometimes based on freaked-out emotions.  And when they realize that they've said/done something really stupid, they understandably get even more upset/concerned.  We weren't advised of this expected reaction till we asked "what's going on?".  It's not supposed to be a permanent condition (the jury is still out for my friend - she only just finished the treatments).  Be aware of it.  Don't let them handle money (My friend got a wild hair and just had to have some light painting done.  She hired a 14 year old, who did a half-assed job - it will have to be completely redone - but he was a nice enough kid slowly using a 2 inch brush on everything, big or small.  He proclaims he's done, she pays him $700 - about $12/hour - plus a $300 bonus>>>>>Chemo-Brain!).

These were the most profound things for me/her.  Best of luck to you.
