Hello,
I was suspecting something similar! My Depression had gotten way worse after ayahuasca ceremonies last year (March 2016). I guess ayahuasca removes the heavy metals and a "regular" person can get them out of their system which is why so many people feel better afterwards. Bad detoxers like me (due to MTHFR and Poluria) will have problems getting the metals out. Maybe that is also why they generally not recommend ayahuasca for schizophrenics or bipolar (which probably most likely are cases of heavy metal toxicity due to inability of detoxing).
I have two ceremonies coming up soon but now got scared if it is a good idea. I am detoxing metals at the moment with MIcrosilica and starting my polyria treatment with B vitamins etc. I was wondering to maybe try the aya but take a big amount of binding agents like Microsilica and charcoal afterwards to get the shit out. It is scary but I guess I will give it a try and will let you know (if I can)...
Did you have another ceremony in the meantime, darkmoon?
