Hey John of Arc, I pray you went back to work despite mucous. I am in the same boat. My last rad treatment was 10 July. It was then the mucous really started to develop. I was hacking up phlegm balls every 5-10 minutes (or else swallowing them). I also got a suction machine which made it easier to remove from my mouth. I did not have to hack it up which hurt a lot. Today is three weeks post last treatment and mucus is almost all gone. I still have a little, but not as large volume as earlier. I hope this helps for comparison. I hope you are ok with your employment. I am working towards going back to work in a few weeks.

Ken
