what does it taste like. would French's mustard work?

Over the counter drug called Leg Cramp it's my sold at Walgreens, ITS A LIFE SAVER FOR ME

Eat banana's your body needs potassium. That's what my doctor said to me when I was having leg and arm cramps.I don't want to take anymore medicine.

I think the mustard is similar to the pickle juice--acidic ??
My Great Grandmama used to say to put a bar of soap ( Irish Spring ) under her sheets at end of bed. It did not work for me but I told a friend and he swears by it !!
