Thanks for posting on this interesting topic. Yes, I have done quite a bit of research on RLS as well and have plans for another volume of FTD that will include RLS in a basket of autoimmune/systemic conditions linked to SIBO. And the iron deficiency connection is indeed fascinating.
I could start another forum for RLS, or just leave it as you have created it in the autoimmune forum. Let me know if you have a strong preference.
