Negative Positive
Title: Great Product!
Review: The reason I started using this stuff was because I was cramping all over and had terrible fatigue while playing tennis in the summer. Since then my cramping is gone, fatigue has dramatically gone down and i'm extremely happy with this stuff. I haven't used other brands, though i suspect they all work to some degree, but I sweat profusely and get dehydrated easily and while using this my tennis game has gone up along with my energy levels.
