I had daily Ethyol shots over 6-1/2 weeks of IMRT for tonsil cancer (with two lymph nodes). I was given anit-nausea medication, settling on Zofran wiich worked very well for me (the first one, phinergan or something like that, did not work so well).
Everyone reacts differently, and my RO was adament that if the Ethyol gave me any problems which would impact my radiation treatment, I would have to stop using it. But I made it through.
I am 9 months out and have very good saliva (not great).
I am not aware of any specific benefit of Ethyol to the taste buds, but I have virtually fully recovered taste (I am 9 months out of treatment). During treatment, I lost almost all sense of taste - and eating was very difficult for that reason and others.
Best wishes,
Chris
