In addition to the good advice you've gotten, my tip is to watch the radiation burns very very closely and press the doctors on what creams or ointments you can use. There are specialty gels for radiation out there that I found out about too late The aquaphor did not cut it for me, and I ended up having to use Vigilon second skin burn dressings. Also cannot stress enough the importance of keeping up the jaw exercises - if you are lucky like I was, then you won't need the therabite. Finally, take the pain pills - they really help swallowing and sleeping - for constipation I found suppositories the very best - much better than laxatives or stool softeners. Good luck and there really is light at the end of this tunnel.
