JoAnne,
My father is on almost the same timeline as your husband. He had a left modified radical neck dissection 2/10/06. He began chemo on March 7th and radiation on March 13. His primary is unknown so his radiation is pretty much everywhere it seems. We are in the fourth week and it is getting pretty tough. My father is also taking the Ethyol and doing ok with it so far. Thoughts and prayers are with you and your family!
PS - My father also never smoked etc and was a very healthy person until this. He is 66 yrs old.
Keep us posted as you progress.
