Hi Shroom... this self experimentation is something else eh? I wondered your opinion on how parasites cause panic attacks. This was a MAJOR symptom for me for a long time...whenever I tried herbal anti-parasitics, I'd get panic attacks. It still can happen if I take a big dose of something, just not as bad as before. Do they release some chemicals that spark panic you think...I've never known the mechanism, but it definitely was coming from them, especially when they feel threatened. I also noticed I could sometimes stop the panic by taking a large dose of digestive enzymes...and I could feel the parasites actually move out of my stomach. The panic sometimes stopped when this occured. Something they are releasing directly into the tissues maybe?
