I really thought there was something wrong with me, that I was slowly dying of something they couldn't determine.
I came to eventually determine the cause. Diet soda
. I was drinking a lot of diet sodas
, chewing sugarless gum, using toothpastes and mouthwashes, and taking Airborne, all containing aspartame, sucralose (Splenda), sodium saccharine, or some form of artificial sweetener.
