My (now former!) doctor started me on Armour Thyroid several years ago, although my lab work indicated there was no problem with my thyroid. About a year ago she increased my dosage from 30mg to 60mg, and wanted me to increase to 90mg and then 120mg. When I took 90mg, I started having heart palpitations and frequent sweats, so I went back to 60mg. For the last 4 months, I've had debilitating diarrhea, nausea, weakness, sweats, shakiness, sleeplessness, etc.
