My understanding is they went by the tsh. Other than losing weight I never noticed a lot of difference on or off the medication. I took .05mg. Thank you for your input.
You were on a pretty low dose. It would be nice to have FT3 and FT4 to confirm, but if you feel as well now as you did when on meds, I guess you're no longer hypo! Congratulations!
How are you feeling off meds? How much Synthroid had you been taking?
