Hi, I thought it may be helpful to someone if I updated on my progress with doses and observations about the brand differences, continuing from my reply above.
I had my blood test on 30/12, 6 weeks after starting 75mcg. All of the time I was taking the MP 25mcg with 50 mcg Almus and then MP. Throughout the whole 6 weeks I never felt particularly well, it felt there was only a tiny improvement from where I was towards the end of the 6 weeks on 50mcg (when it all dipped). I increased my dose to 100mcg on the day of the test (after) and took Almus 2x50mcg, then 2x50mcg MP for the last 3 days as I ran out. I have been feeling great again for the last few days 🙂
I saw my GP this morning and my tsh was 3.58 I.e. It has not improved much. The GP increased the dose to 100mcg and I collected Actavis 100mcg tablets from Sainsbury's earlier today.
It feels that the 75mcg dose did little to my tsh and it reflects how I felt: not much better. I will now take solely Actavis and hopefully things will be different at next blood test. I now seriously wonder if the MP pills do have the relevant strength or something in them is hindering absorption?
