Quantity consumed varied from day to day. It was generally one to three 12oz glasses.
I was operating under the assumption that it was the same condition that I had successfully held in check with CS many years earlier. After a couple years, I did a crazy supplement protocol I got from a medical intuitive, and the condition cleared up for 11+ years, except for the occasional flare-up when I'd eat the wrong food or get really run down. The only CS I took during those 11 years was during the flare-ups.
A few years ago, the same condition seemed to have returned, and I started taking CS for it. However, this time, it wasn't working. So, I ended up guzzling even more of the stuff because I was so convinced that it was the same low-grade infection from before. Finally, an ooga-booga muscle testing chiropractor determined it was fungal and that I needed to take a supplement I could only buy on the Internet (blackmoldrelief.com). I took the product at a higher than recommended dose, per the chiro's instructions, and it cleared it up in about a month.
My CS is homemade, using distilled rainwater and pure silver with the Colloid Master from wishgranted.com. Because I added a stirring mechanism, my CS is crystal clear instead of pale yellow. On a Hanna PWT, it measures a little over 20 uS. My distilled water measures around .8 uS. No added salt or anything. I had been led to believe from earlier online discussions that argyria was impossible to get from CS in the 20 PPM range. Turns out, they were wrong. Granted, mine's a very mild case, and it has faded quite a bit. Some people don't even notice it; some people stare at me. Staring most often happens in stores with fluorescent lighting. It was never scary blue like Paul Karason.
