oh my dear madam.
I am quite sure u were very comfortable when u were on 100 mcg of eltroxin
what many people don't know is that thyroid
is managed both by clinical symptoms and blood tests.
so I suggest u go back to 10 mcg.
take care. don't get driven by TSH
Look at ur free T3, free T4 levels if they r in normal range then don't be bothered at all.
God Bless You Madam
