I dont chew gum, and I never eat anything that has artificial sweetners in it. I could see how that much friction could cause some soreness tho.

My tongue is already some better. I doubled my hydration today, and have avoided sugar, and salted things. I see those brownies on the counter, and have to close my eyes! I will use a baking soda rinse before I retire.

I was doing some research and this is very common. I was impressed with how many folks report this condition. Since the DH has it too, I am gonna assume its one of two things. 1. either we both have become acidic with our diets, or 2. its a virus.

Truly odd.
