iodine deficiency

Hi im a 3oyo female Who has had hormonal problems for the last 15y and Arthritis for the last 20y I have finally been diagnosed with Iodine deficiency and have been taking supplements for just over 3 weeks now, I have started to experience emotional hysteria, before I stared the supplements I suffered from severe pmt but now it's like extreme pmt most of the time, has anyone taking Iodine supplement found that it increases emotions to begin with?
