    sleeping aide

    Posted by Reviewer3007857 on Dec 26, 2007

    This is a very gentle yet effective product for insomnia and restless nights. I use it nightly, and awaken alert each morning.

    This is a wonderful product. I have fibromyalgia and it really helps me a lot. The 500 mg capsules are wonderful since I take 2000 mg a day.
