I was on 75mcg levo (T4) for years. Recent blood test results have suggested poor conversion of T4 to T3. My endo suggested 50mcg T4 with 10mcg T3. TSH stayed the same (oddly) but FT4 was then near bottom of scale and FT3 off bottom of scale. I then tried 75mcg T4/20mcg T3. Suspecting T4 may be too high now. Various symptoms. So today I tried 50mcgT4 and 20mcgT3. We'll see! Have got TRH test scheduled for 1 May to check pituitary function, so can't change dose (at least not upwards) before then.
So it would be very helpful to chat with people who've been on this journey to swap notes on how things go, particularly in these early stages.
I'm thinking I might well end up on T3 only. Or maybe NDT.
Please PM me if you're happy to share experiences. Thanks!
