Chris;
I don't know if you're a coffee drinker or not.  While in treatment I totally lost my taste for coffee, which I was told that a lot of Chemo patients do, but it would come back.  Well it did, and I drink coffee with meals just to change things up.  (can't stand it hot at this point so I dilute it with ice)  Also, as Amy said, tea goes down pretty well.  Anything carbonated doesn't work at all for me.  Water is still the first preference though because I still seem to require a lot to wash things down.  This is kind of strange but milk burns, except I can tolerate it with oatmeal & cereal (which I let get soft in the milk prior to eating).  After I eat the cereal I can handle drinking the milk.
Best Wishes,
Steve
