JAMOS -
If you haven't already done so, you have to stop the tobacco use BEFORE radiation therapy: I can point you at the studies that show that smoking reduces the effectiveness of the therapy. I know the timing is horrible, and that tobacco is terribly addictive, but this is one thing you DO have control over that can make a difference in your outcome.
If you have to carry cigarettes, tape them in a plastic bag, and tape pictures of your familie over that: maybe that will give you strenght. Also, discuss smoking cessation with your doctors - there are patches for that, too. Please, please, please try to do this.
On a more positive note, my husband's ear ache subsided a couple of weeks into therapy, so I am hoping you will get some relief soon.
