Bobbi – Thank you for the response. I realized fatigue, etc. could be symptomatic of both hypo/hyper. The weight and concentration things, by all the web sites I looked at, were exclusively hyper. Such was my dilemma. Your pituitary comment is very enlightening and makes sense. We’ve reduced my dosage and we’ll check it all in a few months. I’m trying to get educated enough to ask intelligent questions of my doctors. They’ve been great. I’ll do a follow up post.
