too much iodine?

hey,

maybe anyone can help me with this. when I started Iodine, esp between 2-6mg (potassiumiodine only) I felt great... I did have sideeffects like bromide Acne but I had a great feeling in my mind, like the feeling you have, when you're on holidays, far away from your everyday problems - but I had that without holidays. ;)
now I have switched to lugol(5%), built my way up to 8 drops which should be about 50mg(for about 2 weeks now), the bromide Acne stopped (which I would say is a sign for less bromide pollution in my body, so my mind should get better too). But mentally I feel bad. I did and still do the salt loading, I'm taking selenium, vit C and magnesium too... (actually, too much magnesium makes me agressive, although I am aware that it should help calming down, anyone knows why??)

while I wanted to do the Iodine loading for 3 months since I do know that high amounts are needed to get the Iodine in every cell, I feel like this is no good for my body anymore(before, even with the bromide Acne I felt like I was doing something good to my body). recently I read that Iodine over 20mg might cause hypothyroism in some individuals (on the optimox website)...

so, any ideas? anyone had similar problems, if so, what did you do?

any help would be great. thanks!
