I was taking 900 mg for burning feet and I swore that it eased the discomfort by about 1/2 or 1/3, wasn't quite sure. The doctor told me to double it, so I did and really didn't think it did that much. He said you can take up to 3000 a day. I didn't know it was used for fibromyalgia. And I'm not at all sure I have this condition. Just checking it out on the web.. Good luck to you..
