All I knew was that I had Neuropathy and that it was driving me crazy because the pain in my feet was so bad that I couldn't sleep. I then joined the local group in Auburn, CA. where I learned much more with speakers & videos. I was given a sample of Neuragen to try & rub on my feet before I go to bed each night & it worked. Now if I can't sleep, it is not because of Neuropathy. For me the Neuropathy Group has been well worth it & I continue to learn more.
