I thought I would make the move in an effort to rid myself of all 10 symptoms I am currently suffering. My GP said she would support me by doing the 'fancy' bloods I requested however the hospital wouldn't so them for me just TSH (3.0) and Free T4 (15.5). I was hoping for a baseline before starting NDT. My GP wouldn't prescribe this and said she only knew of 1 other patient (12K patients at this surgery). So I purchased Thyroid S from Amazon (waiting delivery) and I am feeling a bit scared to take it as I have read you can feel worse before better especially if the dosage is wrong. So I imagine I start at 1 grain (2 doses) then increasing by .5 grain every 2 weeks. Given I am only on 75mg Levo I assume 2 grains might be the optimal amount? Should I have private bloods to get the levels or just go with my symptoms? Also buying meds from Thailand seems dodgy have I done the right thing?
