I was diagnosed to have chronic fatique syndrome a year ago with muscle aches and easily tired. I had frequent colds and flu like syndrome. I started using Longevity Crystal since November 1998. Within a few days I noticed that my fatique is gone. I have lots of energy to do my work and I sleep better. I do not suffer colds, pharyngitis any more. My skin gets a lot more supple and I am more happy. No longer getting depressed. My friends comment that I look at least 5 years younger.
