and i haven't had any more locked up (spasm ) muscle attacks since.
seems to work real well. look into malic acid tho, found in fresh cherries, apples ect and available in suppliment form.
thats the natural approach anyways... a combination of malic acid amd magnesium is natures muscle relaxer...
read about malic acid here ----- ya have to scrow down to it...
