I've been on thyroid treatment for 15 years or so. I really don't feel that I'm taking enough yet I just get my blood tested once a year to be told everything's fine. A couple of years ago I was given a double dose for a few months by mistake and I felt amazing. My mood improved, I wasn't perminently cold, I remembered stuff etc etc. The GP stopped it suddenly when they realised and I've gone back to feeling rubbish all the time. I'm thinking of finding someone privately that understands underactive thyroid but don't know where to being. Can anyone help???
