At the end of May I had my annual review and my results were TSH <0.5 (0.4-5.5) outside range free T4 22.4 (11-26) results consistent with over-replacement with thyroxine and free T3 4 (3-6). I had expected my results to show I need an increase in medication as I was so tired but my doctor said it could also be because of overmedication. I thought it was more likely that I wasn't converting well as my free T3 seemed relatively low to say how high my T4 was. She reduced my thyroxine by 25mcg and told me to have another test in 2 months. During that time I started to feel worse than ever and my tiredness was about the same as when I was first diagnosed. I had another test after 2 months and my TSH is was 2.8. From past experience I know this is not a good level for me. Because it was within range T3 and T4 weren't tested (the lab have refused to test it in the past when my doctor specifically requested it and my TSH was in range) so I have no idea if my T3 had dropped even more. My doctor suggested taking the same dose 3 days a week and 25mcg more on the other 4. I did that for 2 months but it hasn't helped and now I feel the worst I've ever felt. I've just had another thyroid test plus the usual ferratin, liver function and glucose tests. The extra tests came back normal but the Thyroid was TSH 0.26, which is outside the range again, and T4 18.3, which is lower than before. The receptionist said they haven't been given anything for T3 but I'll ask my doctor when I see her on Tuesday. I feel like I'm going round in circles and meanwhile I get more and more tired. I nearly fell asleep in a meeting with my boss 2 weeks ago which is more than a bit embarrassing. Does this sound like I'm not converting well? I would welcome any comments/advice, thanks.
