I hear you! I also have FMS. Can you mail order the ornithine? It does seem to help, but I have to take at least 6 of the 500 mg. Also, for your FMS, here's a thought:
I have finally been diagnosed with ADD (another reason to do the cleanses) when my son was diagnosed. So now I take medication for the ADD for better attentiveness. The side benefit is that my FMS pain was GONE! Wow. Give some thought to finding a product that will be calming, and another thing that helped me was taking antioxidant blends to help clean out the toxins. Dandelion also helps clean out toxins. Another herb you might try is St Johns Wort, take it at night, I take 2 capsules and it helps calm me so I can sleep.
Unfortunately I have not found a good solution to waking at 2am, but sometimes taking more St. Johns Wort helps me.
