I am the woman cougar is referring to - taking only SSKI and companions right now, and as more brain fog lifts I am realizing the need for Iodine as well. Cougar was kind enough to provide Brownstein's video link and after watching it, a lot has become less confusing. It was something I had planned to do when I started this journey in March - never got to it, but I see why it is recommended. I have recently purchased 125 g. SSKI crystals via e-bay and will now seek 75 g. Iodine crystals to make my own Lugol's, assuming this is correct math.
