I asked endocrinologist to change my Levothyroxine. I was on 100mcg. He prescribed T3 which I got from Greece as others suggested here. I lost the prescription but I'm sure it was 20mg 3 times a day. As the ones I got are 25mg, should I take one twice a day or even try half, four times a day. Also, do I take with food or not and what time would be best. I don't want to go back to Endo until I have tried these for a couple of weeks. Any advice?
