I've been taking around 100mcg levothyroxine for approx 7 years and it has mostly worked well for me, especially after I sorted out a vit D deficiency. I have Hashimotos and a high level of Peroxidase antibodies. Recently I have suffered days when I feel completely wiped out and exhausted, it comes and goes and in between I feel OK but the frequency of bad days was increasing and those periods lasting longer. I asked my endo to test my T3, which she doesn't usually do, and it was 4.0, compared to Free T4 of 20.3. My TSH was 2.35, although only a month before it had been 1.37 which was a little odd. She described the results as showing my free T3 as being in the 'normal range' however when I pointed out that it was low compared to the free T4 she agreed to trial liothyronine.
However: she said to take 20mcg on top of the 100mcg T4 and I wonder if this is a good idea. I am on day 3 and today suddenly feel very weird - I had a slight headache and now feel quite 'out of it' and wobbly. I have emailed her to ask if I should a) reduce the dose of thyroxine and b) split the T3.
I'm now convinced she has started me on too high a dose but those tablets are tiny surely it's difficult to cut them even with a pill cutter?
I have been seeing the same endocrinologist privately all along and she is rather resistant to any treatment other than t4 - she started practising in eastern Europe where only natural thyroid supplements were available and according to her the doses were very variable so she won't touch anything like that now.
Will these strange sensations subside once the T3 leaves my system in a few hours? I hope so as we are going on holiday tomorrow! Any advice gratefully received, thanks!
