Here's why I think the hormonal issues are starting to kick in now...at least as I understand it.
Let's say you need to drink 3 cups of water a day to feel "normal."
You start drinking 2.5 cups a day instead.
For a week or two or three, you don't really notice the difference. Over time, the variance becomes larger and the difference more pronounced.
The Cytomel-one size fits all-is the 2.5 cups per day for me. After the radioactive iodine process, I'll be on Synthroid...They will figure out what my appropriate level is-through a trial and error approach that could take a few months-before I'm back to 'normal,' whatever that is anymore.
