I had gotten myself to around 18-21mg of Prolamine Iodine, before I switched to Iodoral. Then began on iodoral @ 25mg for one week and the next week skipped to 50 mg (I have been on this dosage for about 2.5 weeks). Ironically, I have had less side effects from Iodoral than I did Prolamine Iodine @ much lower dosages (although I have seen others on this forum and on Iodoral reviews on Amazon attest to the same thing).
The most discomfort I have had on the Iodoral thus far was constant sneezing and a runny nose (when I upped my dosage to 50mg), but, that went away after about a week.
I think my coldness was attributed to my low blood Sugar from not eating for about 12 hours. Once I ate, I warmed right up within 30 min after my meal.
