Wendy, for some reason or other, some do better on Synthroid than the generic form, even though they are supposedly the same thing. I'm on Synthroid now, but have been on generic before. When I lose weight, my TSH really drops and I start going hyperthyroid, so need my medication dose reduced. Also try taking selenium if you aren't already. It revs up the thyroid and helps it work more efficiently. Many people are able to reduce their med dosage when on selenium.
