These two sites have some interesting info. I came across this guy, Dr. Lowe, (not sure who he is or how reputable he is, so I'm not trying to push his stuff, just thought that it sounded plausable). When I was first told that I was Hypo I thought of my mom. She has fibromyalgia. I asked her if she had been tested for Thryoid issues, and she said yeah, but back in the 80's. I have encouraged her to be tested again, hopefully she will look into this guys info. She complains of tired aches and pains... and I used to say... yeah I'm exhausted too. She has worried for a long time that I might have fibromyalgia.... now I'm worried that she needs thyroid help!! Who knows maybe these two a intertwined!
I think that the free t4 at 1.5 is good. You want it at mid-upper end of the range to feel good.
To check to see if you have enough t3, you will need a free t3 test.
Isn't 1.5 kinda high even though it's in normal range with a dose of 150 mcg? I have not been tested for those things yet. Someone told me that I might have a conversion problem. Does anyone know about that?
Your TSH and free t4 look great.
My endo considers adding t3 (Cytomel) if there are still hypo symptoms.
Have you had any adrenal tests? 8 am Cortisol, ACTH Stimulation Test?
Here is an article that brings up the possibility that Fibromyalgia may be an endocrine disorder.:

Consider trying a brand name levothyroxine product like Levoxyl or Synthroid. Some here have reported feeling better on the brand name.
