Oooh. Damn. I've heard of a more serious version, that has a name, but I can't remember it. Hopefully you haven't inherited something serious. I have terrible cramping issues, I wish I had known how much magnesium helps, it's essentially the conduit to which the electrical signals controlling your muscles ride around on. I have found magnesium glycenate to work best for me, there's heaps of varieties. I hope you find one that helps, crossing my fingers for you!
