RedRocks,
Now that your hair is thinning, that's a sign it's not magically healing itself on it's own. Hairloss is classic hyperthyroidism, and happens to us hypo patients when we're over medicated. You're exhausted because your body is on overload 24/7 from all the thyroid hormone racing through your system.
We've "talked" offline about this. So sorry you're going through it. I'm working on adjusting to my new dosage as prescribed last week.
Take care
