I have a app with nurse at surgery next week for 12month MOT. i have been suffering with all sorts of problems, taking levothyroxine [150ml] but still have all the problems that a under active thyroid can throw at us. my reading keep coming back as normal. just wondering if any one has had the 24hr adrenal saliva test and was it set up by surgery. at the moment i am cluching for straws. Dave.
