I had a thyroidectomy 8 years ago and my doctors have changed my synthroid dosage 2-5 times a year. this year, so far, twice. my blood test last Saturday was t4 1.1, TSH .60 but my T3 is 69. I'm tired, want to quit my job and school, have lost hair and have gained 15 lbs. this year. I'm on a combination dosage of 112 mcg of synthriod and T3 5mcg.
