Hi. I was diagnosed with fibromyalgia. I have about ALL the symptoms connected with the disease. Doctors couldn't help me at all and no amount of painkillers could give permanent relieve. I am taking 2 teaspoons in the morning, otherwise I can't sleep. Only thing I should mention to you, if you find your msm is working for you, check and see how much chlorine do you ingest per day from your drinking water? Msm should not be taken with tap water as the chlorine in the water "cancels out" the effectiveness of the msm. Sounds dumb but its true!!!!
