Thanks so much for the response. What are your symptoms? This is all very new to me. I've never had ANY issues like this, and I think it came up as a result to taking methyl supplements for methylation and having a negative reaction to them. Things haven't been the same for me since. I shouldn't even messed w/methylation b/c mine wasn't bad. Homocystine was ok.
But now I get this terrible head pressure. It manifests in different ways, but it's my primary symptom. Over the past 2 wks, it's progressed to difficulty breathing. Do you experience these symptoms from histamine?
