Re: Withdrawal? My body feels like it's going crazy!

Gregory,
"I feel very cold, my toes & fingernails look blue and I'm feeling very foggy. just feeling very bad right now."
IMO, you have the symptoms of severe hypothyroid. I suspect that you have set off Hashimotos by taking iodine without selenium. Spend some quality time to read this:

Especially read the importance of selenium here. This file just came in, many thanks to Violien:

When you get your selenium, consider following the doctors advice quoted above to take selenium for 3 weeks before starting your iodine. You might also want to monitor your thyroid antibody levels with the inexpensive at home testing kit, or get help with this from your doctor.

I also suggest you immediately begin charting your body temp to monitor your thyroid metabolism;
