All I know is I had a very mild IBS (no medication) and after my TBI it got worse. Now if my stomach gets upset then all my PCS symptoms gets multiplied by 10 times. The reason I take Elavil is more to keep the stomach calm than anything else. Recent study shows there is a direct connection between brain /gut. Some times even I think my anxiety is coming from stomach.

I had no problem with wheat now I avoid wheat whenever I can and sure my stomach behaves. I am even thinking of gluten free. I take low dosage folic acid (400 mcg) and it comes with B-12, B-6 and Biotin. Hope it is not causing my brain fog.
