Hi, Terry,
Congratulations on finishing your treatment!
I am now four and a half months post radiation - did not have chemo. Mouth is very dry, but carrying a water bottle is not that bad.I had IMRT, so I have hopes of leaving the bottle home one day.
I can taste probably 50-60% of "normal" - waiting to taste sweet, so many things depend on it. I eat mostly vegetables, lots of yoghurt, I can eat croissants with lots of butter. Cheese started tasting good last week - hooray!! I stated on yoghurt smoothies, then cream soups like shrimp and mushroom (first without the shrimps and mushrooms) at about five weeks post radiation. Recovery seems so slow when it is happening, but things will get better, only you'll have to count weeks, not days.
And, the mucous will disappear in about six weeks. Mine turned white and then clear and stopped being a big problem - all of a sudden I did not have to spit into a tissue every two minutes. i could not believe it was gone! It happened very quickly.

As Gary said, patience is unfortunately what you need. Good luck!
