Hi Scanders -
Our thyroid gremlins keep us guessing, don't they? Like you, I know that FT4 at the bottom of the range is no place to be for me either, so I've been trying on various spots for size, in that wide range - with increasing doses of Synthroid now. (I was taken off Tapazole last year, because my TSH would slip higher ever other lab, as we were decreasing my doses). What I have learned is that “close, but no cigar” is so true with thyroid levels - speaking for myself, they've got be be bang on, or my body is just plain not happy. But I'm closing in now, with each small Synthroid increase. I hope that the tiny dose adjustments you and your doctor are making, will put you back to your happy spot really soon! Keep us posted, and keep the faith,
… there was a star danced, and under that was I born.
