Well, it seems that the more I want to be normal, the more whacked out my body gets. I have been on T3 since last May because apparently I have Thyroid System Dysfunction. Last week, I had to have blood drawn to check the thyroid numbers again, and now it turns out my T4 is low. So, I am continuing T3 and am going to start Synthroid. Good grief. This is all so strange to me. I have never known anyone in my family to have a thyroid problem, and now apparently, I am riddled with them. I am kind of nervous that taking T3 is causing me problems. I mean, it is hard to believe that I have a problem with an organ that I don't even know what it does and can't see it. And, I've lived most of my life not knowing I had a problem. I guess I need to just let it go and continue to trust Dr. H and God. But, I tell you what, I am tired of "popping pills." Is anyone else out there taking Synthroid, or has taken it in the past? Is this going to be something I will have to be on forever, or will the problem correct itself within a few months?
