My bs did settle down eventually but can be still baffling. At least my thyroid function is now within range even if my bs aren't! Good link from the person below.
That's the biggest thing I can't get my head round no two days the same and then the thyroid meds completely threw me. At least you were given the advice at the start that may need to increase basal. Don' really understand the t3 or t4 difference so going to Google it now!. Presuming the nhs are not going to take the thyroxine off me Thank you for your response
