I have fibromyalgia and have been taking Diatomaceouls Earth for almost 2 weeks. It is definitly doing something positive for me. First I noticed a huge change in my foot problem that has plagued me for 4 years. I have woke up stiff, but that is different too. I don't know how to describe it except that the stiffness is not to the bone and all encompasing as before. I am so hopeful that I may continue to improve. If it is possible different factors contribute to Fibro for different people, I guess different results could be experienced from individuals also. My experience would lead me to suggest, try it and see how your body responds if you suffer any joint or fibro pain. Good luck to you all!
