Can't speak for myself, but my H says it tasted bad - all bad. Not even like nothing, just bad. It started for him after 2 weeks, was full blown by end of week 4. He was getting RT on both sides of his neck. It lasted about 3 weeks after treatment finished.
This time, it isn't so bad. He is about 12 treatments in, just on the one side, and his taste is ok still.
Emend was the only thing that worked for H's nausea. Compazine, Kytrol, etc. etc. not enough! A miracle drug indeed. They can also give you drugs via iv if you are really having trouble. Ooh - they just gave him a kytrol patch that has helped too.
H could taste vanilla stuff the longest - he did vanilla ensure shakes almost exclusively by the end.
I hope you feel better!
