Sounds like you have already been through a lot . The radiation will probably be troublesome for you. I did not have any radiation of my mouth, just my neck. I used a cream, Biafine on my neck that worked beautifully. I never peeled and unless you knew I was having treatment you would not have known. The Biafine is not greasy, my whole neck actually looks better. The mask thing bothered me some, especially farther down in the treatment when I would cough etc while in treatment. I was initially surprised that during treatment, you feel nothing. The techs played an FM station while I was on the treatment table. I figured out my time was about three songs plus ads, haha. I would tell you to eat as much as possible now. Even though I had no lymph involvement, my RO increased the field of my treatment of my voice box to catch the lymph nodes adjacent. He called it microscopic treatment for anything that might not of shown up on my initial CT. Good luck. I think the hardest part may be behind you. I will start my after treatment scans soon and praying nothing shows up. I basically have been in limbo all year so far. Time to get better and have some fun.
