Joanna,
I am glad to hear others survived amifostine as did my mom. Your mouth will be feeling the effects of the drug and the radiation, but keep a postive attitude and that will help. My mom experienced the side effects of the treatments fairly soon into her treatment, about 1-2 weeks which was a surprise to the docs. So she has been pretty much on a liquid diet; cream soups, puddings, egg nog, protein shakes, water. So get out the blender and get creative.

I look forward to hearing how it all goes for you, as I feel like what my mom went through was tough. So I hope to be able to support you in any way I can, even if it is only through reading about it!
