Im sorry youre feeling down Sanctuary. I would definitely continue the iodine. I think its released toxins that make you feel depressed. Those have to come out and Iodine is the way to go. Hang in there, it will get better :) I too have a day sometimes where I feel really down, but I know its the toxins and it will pass. I look at it as proof that Im doing the right thing taking iodine. Same goes for headaches, allthough since I salt load twice a day I dont get those at all anymore.
Are you taking the supplements such as Vit C, magnesium and selenium? Do you salt load regularly> I notice I need to use 1/2 tsp salt instead of 1/4 to feel good.
