Before I was taking Vit D I was waking up feeling unrefreshed , and exhausted every moment of the day, all the main fatigue symptoms of Fibro. Once I got my Vit D to a good level (I was VERY deficient) ALL of my fatigue symptoms went away. It felt like a miracle. I actually go through my days now without being in a fatigued state. And with my Tizanidine to help me sleep I take NO naps during the day anymore!! It’s crazy!! I still experience the other symptoms of fibromyalgia like pain but I feel so much better now my Vit D is at a stable level. I suggest anyone with fibro get all there vitamin levels checked out. It’s been amazing to actually feel the energy I thought I lost forever.

My dr rx me 4,000 iu of vit d a day. I live in Southern California, n still vit d deficient.

Vitamin D is very beneficial for depression, sleep disorders, pain, etc.

I do take 4000 mg per day of D 3.and my pain level is low plus everything else I take

I have trouble with Vit D deficancy. I took 50,000 units of D3 once a week for a month. Levels came up and went on 1000. I was terribly tired. I would come home from work and fall asleep. My legs hurt. I had no problems after that. This July the first set of tests the rheumatologist ran showed i was deficant again. I did another go of 50,000units. It is back up to 34---bottom of the range is 30. Rheumatologist said that was good. I've read where it should be higher. She has me on 2000 once a day. Problem with Vit D is it's fat soluble. If you are over weight your extra body weight tends to absorb it. It doesn't do what it is suppos to do. That is what my doctor said. I know they recommend you take it with the fatest meal of the day.
