As some of you know I have been hypo for nearly 20 years and am on 175mgs of levothyroxine. To cut a long story short I paid and had private tests in hopes it would show a conversion problem. Which it did. I saw a gp at my local surgery who agreed to prescribe me t3 only. I was taken off my levo and put on the t3. It really did not suit and my own gp put me back on levo only as I couldn't function. I asked her to refer me to a private endo. She said she would write to a local nhs endo to ask advice and if I wasnt happy then she would happily refer me privately. The letter came back today and the endo has agreed to t3/t4 combo. He had suggested dropping levo from 175 to 100 and adding in t3 of 10 twice per day. I am a bit concerned about dropping my t4 so much and adding in so much t3. I think I will leave t4 as is and add t3 in of 5 and gradually increase it and gradually reduce t4. Really pleased that the gp listened to me and that the endo also agreed to help without seeing me.
