I tend to stick to older, tried and true medications. I refuse to take Cymbalta and Lyrica because of the side effects, which to my mind outweigh the benefits. My doctors don't like that, but too bad, it's my body, not theirs, and they don't have to live with those side effects.
I, too, take Armour Thyroid (and I will look into the NP thyroid. Interesting...) because many people with fibro are hypothyroid, or borderline. I do feel better with it. Ask your doctor for a full thyroid panel if you want blood tests.
I also take Vitamin D3. I was on prescription D3 for awhile, as my levels were almost nonexistent. Vitamin D3 is another one of those frequent low levels for us, and can be checked with a simple blood test.
Eating gluten free has made a difference for me. I've been gluten free for about 4 years, I think. When I 'get glutened', the results are joint and muscle pain, and fibro symptoms. It's a pretty clear cut correlation for me.
You might want to check out Fibromyalgia Network. I subscribe to the journal. It's a keeper, at least for me. No advertising, just real and useful information about fibro.
Just thoughts. Welcome aboard. This is a great place for creating a lifestyle for reaching a healthy weight and healthy lifestyle.
