Well... Back when I was diagnosed in April my doc wanted to check my vitamin D levels. I was asked to sign a waiver since my insurance most likely wouldn't cover the cost of the lab test, costing me 200.00 out of pocket that I didn't have. I did NOT take the test. I just could afford it.
My best friend (oddly and eerily) was diagnosed only 2 weeks after I was, and her doctor put her on a really high dose of vitamin D. It seems that according to a few studies (Google Vitamin D and Fibromyalgia) the majority of people suffering with fibro are deficient in vitamin D, or are on the low end.
I finally broke down and bought some since the MISU has a new, better paying job. Yes, I splurged on vitamin D ;) I have taken it 2 days now at bedtime (2,000 IUs) with a snack and children's gummy vitamins (with 400 IUs) since I haven't found an adult multivitamin yet that doesn't make me have nausea and vomiting.
So far so good! I am happy to report that I wake up almost pain free, where as I normally wake up with pain in a 4-5 out of 10 (max pain) or will develop that level or more throughout the day. Today we went shopping and I didn't have any significant pain until about 530 or 6pm. AMAZING.
Also I was able to enjoy the day and not feel continuously fatigued today and yesterday.
If you suffer from fibromyalgia and have not checked your vitamin D levels , it's worth asking your doctor about it and how much you should take.
