If you still have had symptoms with a lower dose, I suggest that they should also be testing you for Vitamin A, D, B12, ferritin,
and a full
iron test panel. Many hypo patients find they have deficiencies in these areas as well
and can have some symptoms similar to being hypo. Same as with Free T3 and Free T4, just being anywhere within the ranges for these is not optimal either. So I really think you should have these checked out as possible contributors.
