Thanks, Ginagirl! Yeah, I've had more of the pounding heart symptoms. Did cause pretty bad insomnia one night. I have been taking Melatonin at night to help make sure I get enough sleep.
Ok, I will temporarily stop the B-complex.
Thanks for answering my question about the Selenium. I am taking the methionine form. I just wasn't sure if I needed a bit higher dose of it with the higher Iodine dose and possible hypothyroid.
I have some gelatin at home and will also try that if it persists.
*Other observations from taking higher Iodine dose - very vivid dreams...sometimes terrifying ones! Also, my bowels are functioning much better...was having only 1 bm a day (or every other day), and now up to at least 2! *
