Hi Pooky, I so understand, we all understand.
As treatments go along it can get rougher for some, not everyone.
Four yrs ago I had treatments every 3 weeks and the third week I was in pretty good shape and like you having to go back in on Friday for another dose.
This year on Taxotere every 3 weeks I didn't get any break really. I'm older too, that may have been part of it and other medical issues came along.
I sure hope things settle down for you, let us know,
