Jennifer Oroxine is synthetic thyroxine (i take levothyroxine - same thing but generic brand due to NHSness) and it replaces what Sarah's body isn't making, so it is completely safe for bfing and might even improve her supply (i had undersupply of which my hypothyroidism was certainly a factor). Really, though the diagnosis is crappy (having to take meds forever) Hashi's is far more easily treated than Graves disease (which is the autoimmune disease with the opposite effect - makes your thyroid OVERactive) and has far fewer complications.

Sorry for butting in Sarah

ETA - LOL Sarah - JINX!!!!
