Hi Elena,
It seems that everyone reacts differently to radiation and that the recovery of taste also varies individually.

I've read posts on this board from foks 5-6 months after radiation who report they are eating everything and that the sense of taste has returned. Others report taking much, much longer.

My personal experience was that it took about 9-10 months before my taste stabilized. I can't say it is exactly the way it was before radiation but it is certainly much improved since all the taste buds were burned. My sense of sweetness remains compromised, I have to eat very sweet things to get a mild sense of sweetness. There were some foods I couldn't eat for the first year as they tasted too foul - fish, maple syrup, olives. Still can't eat olives. But, things improve with time and eventually stabilize.

At some point, I think you get used to whatever recovered sense of taste you have, and forget what things tasted like before radiation. Hope this helps. - Sheldon
