Sucking ice cube during IV chemo to stop sore mouth

Hello Triton
I went to The Mount Hospital in Perth for chemo.  Had AC & docetaxol.  They gave me an icypole for the red part of AC each time (it was the normal for that one) but not for any of the others.  I hate icy poles so took in an icy water bottle that I was allowed to have (as long as I kept sipping it!!).  I didn't get ulcers but did get a sore mouth from docs - should of tried the icy water for that.  Worth a shot, extra fluids definitely wouldn't harm anything.
