Something you once said in another post made me go out and buy the strongest dose of Melatonin I could find. It seems to me like the herbs work much better when I take it before bedtime with an evening dose of anti-parasitical brew.
There is an allergy doctor in Austin, who is treating just about everything with hormones. He seems to think that balancing the hormones is the key to curing anything.
His clinic is much more upscale and professional than the website. He apparently has a foundation for the study of hormones.
I read somewhere that allergies are an early symptom of parasitic infection. If you are correct about parasites using the neuro-pathways, and if hormones affect the neuro-pathways, then I think you might find this guys research very interesting, and helpful. I'd like to go see him, but he's very expensive and I don't have any insurance.
