Hi Eric. I'm wondering what your process has been with this. I'm in the same boat with very similar symptoms, which I've seemed to pinpoint to a Histamine Intolerance and gut dydbiosis. I'm wondering what tests you ended up taking, what helped and what didn't? I could use some guidance as I just tried going on the GAPS intro diet and ended up flooding my body with histamines (that's how I figured out I had a Histamine Intolerance ), and I seem to be reacting to everything right now! What did you discover, and what has worked for you? Thanks!
