Thanks Meep. Been on 175mcg of Synthroid for years. Planning on trying Eltroxin at 200mcg - should have it in week or so. Gave up on my Doc as the only thing he will test for is TSH - says that is all that matters. So, I started going to a mobile lab which was the result I gave you. I ordered Eltroxin overseas as no prescription is needed from the USA. Will try it for a month or two and go back to mobile lab. Thanks again.
