Does a Bar of Soap cure nighttime leg cramps?

i get cramps all the time, and the reason I get them is due to my high frequency and intensity of my aggressive exercise routines...by default, I become delepleted of my electrolytes (as well as a drop in my water content).  This tactic is not for everyone, I am physically strong and capable of such extreme stress.  Nonetheless, I fully endorse everyone to partake in an exercise program conducive and compatible to the individual...it will improve your quality of life.  I promise!

So, back to my question...
Can a bar of soap cure nighttime leg cramps?
Many people swear that it can....
So how and why?
