Hi DonnaJean,

I am a year out from radiation and some of my tastes are just starting to come back. I lost chocolate (which all women tend to sympathize with) but other things are still shifting and changing.
Not sure about them just "turning off", but maybe it is one of the continuing side effects that builds up?
I don't think anyone can tell you how much saliva or taste buds will return, but you will hear a lot about patience on this website whenever there is talk about the after effects of radiation.

Take care,
Dinah
