So.. I have 4 tablets left of my synthroid, i just called my endos office to schedule some labs as ive been really tired and feeling down lately. I am on 112mg, but before that was at 200mg. The reason for drastic drop was to start fresh and work our way up to see where I need to be. I really don't want to wait til October for labs, if I'm starting to feel like crap lately. Could it be too soon to do labs, and should I just finish the last 4 tablets then do my labs? My endo isn't the nicest guy, I'd hate for him to say I should have finished the whole Rx.. The nurse went ahead and wrote up my labs, I just want to make sure he go by an early reading, and not chew me out for not taking the last on my Rx.
