You may not need cytomel -- you just might need a higher dose of synthroid
or maybe even a different med, altogether. My pcp started me on synthroid
and I didn't do well at all, but when I started seeing my endo and he approved the use of generic levothyroxine, I began doing much better.......
You might also want to consider the use of natural dessicated hormone. I have never used it, but I know there are quite a few on this forum who do and they do very well on it.
