I had radiation only and my taste started to come back at 3 mos and was pretty much back at 6 mos. Although I am 8 mos post now and I would say in general my taste is 75%. Some things a lot less. Sweets@50%, garlic my favorite I still can't taste. Tomato sauce tastes more spicy when it use to taste sweet?
My sex drive was reduced to nothing during treatment. It has recovered a little since treatment but doesn't seem to be as strong as before the treatment.
