Thanks, Billy and JoAnne. I appreciate the warm welcome and the good advice. I am not having amifostine injections. I will ask the docs about that. I plan to read more on the forum about dealing with the effects of these treatments. I did not have a problem with the mask during the sim and the follow-up x-ray, but who knows how the actual treatment will go. I take Klonopin when I feel especially anxious. Thanks again, David
