Neurological symptoms?

Hey all. I'm trying to figure out if my reaction from a peanut butter oatmeal bar was all nickel. Most of my symptoms I know are nickel but I'm also having neurological issues. I have autism/bipolar and it's making me overstimulated and anxious, almost manic. Anyone else have worsen mental health through SNAS? Or could this be a MCAS (mast cell) reaction? Chocolate seems to do the same.. everytime I eat it I just feel manic/overstimulated.
