rlc, thanks for your efforts to bring other perspectives such as Dr Mirza. Also someone, I cant remember, posted a link to Dr Rind and his thyroid scale (did you post this?). I have spent hrs on this and wonder about its validity. I seem to be so sensitive to slight changes in my system and wonder if he might be onto something regarding subclinical levels. Can someone really fel so ill and have subclinical levels? I know how bad I feel and wonder if this might be it, just had blood drawn today looking forwasd to see thyroid paenl results and plug into his scale.
