Three weeks into T3 ,on top of levo (reduced it to 50 from 75 last week, following posts on the forum about t4 being at the top of the range). Taking 10 t3 in the morning and 2.5 (yes an 1/8th of a tab, trying to slowly increase) with not much Improvement. Have felt really ill all day (dizzy, faint, unable to stand up, pale). Called an ambulance - blood pressure a bit high, pulse high, temp OK. GP wants kidney, urea, FBC test done. Thyroid meds already booked for 19th July. Should I go back up to 75 levo and stay on 5 mcg T3 which is what I was on before.Could the 5-htp I have taken the last two nights have done this, or the gluten I accidentally consumed on Saturday in an Indian takeway. Realise my adrenals are a problem and am arranging to see someone to address this. Really disappointed so far.
