You know how you try a product and can't tell if it's really doing something or you're just wishing it would? Well I think this really does work! I'm at the end of a typical ugly January and haven't had a single crying jag which is almost unheard of. I can get out of a sitting position and start walking without a long pause because of pain and basically just have a better sense of well being physically and emotionally. And here I thought my best days were behind me.
