I am going to recommend a beverage other than coffee:
Stash Fusion Green-White Tea
It seems to neutralize and wash the bacteria away. Very nice.
My mouth/throat stops hurting after a couple cups.
You can put the teabags in your pocket. Handy.
Seems to be available everywhere too.
I have also been putting coconut oil in my coffee and tea. It melts and floats on top, but feels and tastes pretty good.
