I hope this post will give some comfort to those beginning therapy. As you will read, everyone does respond differently to treatment. Before my husband started therapy I had read how bad he "should" be feeling around the 3rd week of therapy...sore mouth, gums, sore throat, thick saliva, etc.
Today he finished his 20th rad therapy and he has also completed 4 rounds of chemo. No chemo side effects at all.
Amazingly, so far, it's just a dry mouth and loss of taste, which was expected. He is still eating soft foods by mouth and supplemently with liquid nutrition through the PEG. I guess the biggest thing right now is that he is sleeping more, but he still drives himself to therapy, and stops by and has lunch with me where at work.
I know at some point things will start getting worse, but it's been a real blessing to get this far without any "bumps" in the road.
