sorry you are feeling so awful. If I were in your shoes, I suspect at this point I'd be questioning whether I'd over-done it, although if you are definitely seeing parasites, I guess that's a good thing. I have done some parasite cleansing and have never seen anything that looked suspicous.
In answer to your question, I've heard that 1-3 A.M. is liver time in traditional Chinese medicine, although I don't know if that means it's more active or is resting at that time.
