Sounds very interesting. the article mentions how the mood can be affected, and I have the same condition. I am depressed most of the time. when I speak my voice doesn't have a tone. I am also introverted. Can't even look people straight in the eyes when I talk. I'll make sure to get tested for gluten intolerance. Is it something that you can ask a doctor to do? Is it possible to do? And how expensive is it?
