Christine pretty much summed it up. My thought is that income can always be made, but maybe not your health, so I err on the side of caution these days. I haven't worked since my initial treatment began in 2009 when I thought my small cancer was more or less like a sore throat to deal with, since I thought I was stronger, and underestimated its effect, and more so treatment. Just one misstep, and maybe not even your own, can put you on a slippery slope you may never be able to get out from under, and that's basically what I've been trying to do for the past 5.8 years with 7 recurrences due to my initial treatment stoppage.

Radiation Mucocitis, which is worsened with chemoradiation, is one of the major factors for radiation treatment interruption, stoppage, and hospitalization. Magic-mouthwash doesn't do anything for mucocitis per say, but basic oral care with soft tooth brushing, frequent rinsing with baking soda/salt water, flossing, fluoride treatment, a mouth guard for radiation scatter, and prescriptions like NeuralSal, Gelclair, Doxepin, and Caphosol do, along with pain management, nutritional support/peg, and decontamination of the mouth.

Avoiding foods that are sharp textured, hot, spicy, and acidic will help avoid cut and sores in the mouth that can worsen it, which can also be a route for infection.

Some find, and so do some studies, that manuka honey helps with mucocitis, as well as glutamine powder rinse, which repairs damaged tissue, and adding virgin coconut oil to the salt/baking soda rinse.

The radiation center can spray your mouth out daily after radiation with saline solution, which makes a difference with mucocitis, and thrush, which you'll most likely have also. Extra hydration may be able to be obtained there or in the chemo center, to help prevent dehydration.

Good luck, and seems like you're doing well, so far!
