Others have also mentioned feeling emotional as a result of the iodine. I don't think I mentioned it but the morning after my episode I cried pretty hard for a while, for the state of the world, the suffering and all things I had done to hurt others in my life. I still have some symptoms of my nerves feeling 'frayed' and periodic little emotional 'pangs'.
I'm trying to stay philosophical about it all, but it's pretty tiring to be almost continually stressed in this way. It's funny, but for most of my life I don't think I ever really knew what being "stressed" was. For sure I was stressed as often as anyone, but I don't think I ever really felt it or 'knew' it in a conscious way. Only others could see it in my behavior. I suppose that was a result of me being such a 'fast' person, fast thinking, always observing, noting and cataloging every little detail in my environment. For a lot of other people that would probably be 'stressful', but to me it was always just 'normal'.
