If radiation has the same effect on his taste buds as it has mine, you won't have to worry. The first sip of beer I took a few weeks after treatment had to be spit out. It tasted as though it was full of sugar. Now, almost one full year post Tx it still tastes that way and the same goes for wine. No great loss for me though as I was a very seldom drinker at best. I just miss having a Tecate with my Mexican food. It's just ice water for me now. Good luck with the crisis.
