Well, I had a phone conversation with my GP today, following my latest blood tests (results etc here healthunlocked.com/thyroidu... for anyone interested).
On the positive side, I did persuade her to increase my dose from 25mcg levo to 50mcg - thanks to the knowledge I've gained from this forum, which gave me the conviction to push for the increase, and with a reference to the BMA booklet thrown in for good measure.
On the downside, having thought she might be a good GP to stick with (am already avoiding GP1 who was distinctly unhelpful when I was first diagnosed), I'm not sure she's a good long term option either. As my TSH and T4 were both back in range, she said my results were "normal", and went on to explain that TSH was the one that mattered. Aargh! But, looking on the bright side, she did let me explain my symptoms and their impact on my life, wasn't actually rude or patronising, and did agree to trial the higher dose (though saying it was likely to suppress my TSH - I refrained from saying, I do hope so!). So, my conclusion is that GP2 is an improvement on GP1, but may not be a keeper.
Next bloods in 8 weeks' time, and then I will decide whether to see her again or move on to GP3! There are a number of GPs in the practice, so at least there are several possibilities 😄.
