Hi Denzy
My last blood test showed me to be at the top end of the normal scale and I also had my dosage reduced by 25mg to 150. But yesterday I was at the GP for a review of my tablets - I take lots - and he said to come back if I feel thats not working as some people function better at the top end of the scale. I would dicuss it again with your doc - and maybe ask for a blood test for menopause test as well.
Hope you feel better soon.
