This is my incredibly cagey husband. 
He won’t discuss it. He is over weight and cold a lot, and his previously thick hair is thinning. He’s already on an angiotensin inhibitor, metformin and amlodipine. Not that he’s discussed this with me. I know this because I picked up his prescription. There’s a note saying they won’t prescribe any more until he has had his bloods done, which include the thyroid, bone study, and his usual fasting hba1c. There’s a urine sample pot too.
