I have been taking levothyroxn (spelling) for 11 years but am still tired all the time,
brain fog (a bad thing in company meetings) with worsening muscle soreness, cold hands / feet, carpel tunnel, thinning hair, vitaligo had re-flux too. The docs jack up the prescription every year (was at 175) but my symptoms don't go away. For two weeks I just tried a combo of 112 levothyroxin (t4) with cytomel 5 (t3) in two haves (morning with levothyroxin) and afternoon cytomel only.
