My last provacative heavy metals urine test came back 'negative' for everything. I've done a lot of detoxing over the past few years, so I imagine that was accurate. I had had a little bit of a mercury problem, but chlorella, sauna sessions, colonics, etc. took care of it.
Also, brain fog started to come back a few days after I posted that previous message, so I started another course of drugs and I'm again brain-fog free after a few days (though the first day was rough). My guess is that some eggs hatched. I expect that I may have to go through a few more courses of drugs, but again, so far..so good.
