I just started an experiment with my meds. I have been reading and reading and researching the issues with being hypothyroid. I have come up with the notion that I am getting too much of the RT3 hormone by taking Synthroid and my body isn't converting well to T3. So I have been taking Cytomel, which is just T3 for two weeks now and I am really feeling a difference. You are suppose to do this for about 8 weeks to clear out the Reverse T3, then go back to the regular meds. we will see, but I can say my body temp. has gone up to normal, it has been running about 97.1. That alone is an indication that my metabolism is slow and not getting enough of the right hormones that it needs.
Will keep posting!
