I guess I sort of had my own theory about what I think happened. I also have not much science background, mine is more in the behaviorial field.
But, having said that, I think my body has been producing way too much T4 for a while and just maybe that was my body, or liver's, way of keeping me from going way hyper. Cleaning out the T4. Each time my T4 was way high, I also had a large amount of reverse T3. That may not make much science sense though.
Probably dead wrong. I just ask a lot of questions. The reverse t3 has kept me confused. Is it a thyroid problem, or a liver problem? Mono really did a job on me and my liver.
