I've been up and down on body temp. I typically run around 97.1. After things like my varicocele surgery my body temp would go to 98.6 and be rock solid, but over time it has always trend back towards 97.1-97.4.
I am now trying the circadian t3 protocol 10mcg t3 2hrs before rising to see if it helps and plan to do more to focus on thyroid. Ultimately I hope by adding I HCG and the circadian t3 protocol I might be able to find a system that works for me.
What's "I HCG"? Or did you mean "a HCG"? Also, what the "circadia T3" protocol?
Also, one of my relatives, who is into health overall, tried many combinations of thyroid treatments, including dessicated thyroid or something similar, T3 alone (I believe) and a combination of T3 and T4. What really worked for her was the latter - the combination of T3 and T4. I think she liked the idea of the more natural thyroid, but it didn't work for her.
As I'm sure you know, some people have trouble converting from T3 to T4, so that may be why she had the best luck with T3 and T4.
Anyway, what I'm getting at is that, from everything I read including the Shames book that you recommended, you have to experiment with different thyroid treatments oftentimes before you find the one that makes you feel better.
