Nellie, Amy is right about the PEG. My mouth was so sore I could not hold a thermometer in it, so the PEG was truly a lifeline. About taste, salt comes back first, and sweet last. I ate lots and lots of chicken noodle soup because it has an obscene amount of sodium in it, and I could taste it. When the sweet began to return, I would take one bite and taste normally, and the next would be nothing. I was not until then a particularly patient person, but I learned.
Truly, in a few weeks you will be so much better.
BTW, I, too, finished tx and instead of the planned fishing trip, ended up in the hospital in the same condition you were. Not what we planned, was it? (grin).
