Hi Dick,
I know you did not ask, but here is my experience anyway. I have ongoing
electrolyte issues and have found that potassium works better for my leg
cramps
I know this will sound like I'm way off my rocker. I know I did when a
friend ,{ several years ago } told me to " just try it.." I would get killer
cramps after a 5-6 mile hike...I put a bar of soap--{ I think Caress )
{also use Irish Spring } , some say ivory is best } under my bed sheet...Don't
laugh---I have not had a cramp at night ever since...I e-mailed my friends
with the crazy idea & found that 3 of them do the same thing---one girl
even carries a bar of soap in her purse & has one in her desk drawer to rub on
her leg if she gets a cramp during the day... I typed " leg cramps & soap
" & did a search. It's all there & it works for me...Lois
