I'm already taking Synthroid and Cytomel. The Cytomel definately helped, but still not feeling 100%. Would adding the selenium be too much? My last TSH was 185 and my T3 and T4 were normal (I don't remember the actual #'s) and that was all before the Cytomel. My dr added Cytomel because even though #'s were ok I still had lots of hypothyroid symptoms.
