I probably could have increased the SSKI ; but I figured that Lugol's had plenty of potassium Iodide in the large dosage I was taking.
I agree with the need to increase selenium while on iodine.
I rarely get a cold and have never had the flu; except in 1964 when I had my last flu shot. When I was a kid, I got every cold that went around; so I've become immune to them I guess. When my sinus and constipation problem started in the 50s, I suppose it was not easy to diagnose whether my sinus conditions were due to colds or fungus. And all I got from my doctor regarding constipations was, "Drink more water".
