I passed out after I posted that first comment. All the symptoms the niacin brought on have subsided. It felt like my skin was going to have a sun burn for a while, but my skin is smooth again. I'm going through thyroid like issues with the Iodine but I've read enough to know that's not uncommon. Hair is already thinning right out and I feel like a water balloon my hands and feet are cold and clammy most of the time. Lots of reflux as well. At 50mg of Lugols right now taking it in the morning. I started taking selenium yesterday as well. I'm going to try and stick with 50 for another two weeks then if still having the same issues I will double to 100. Got DMSA on route so I can deal with the lead and mercury that Iodine is stirring up. I'm dealing with a complex bag of problems one of the biggest ones being Lymes or long term mold infection. It's difficult to know which problem of mine is causing what. But I'm pushing on through.
