A Bar of Soap

I have been having some signs of restless leg syndrome.  I go to bed and my legs just jolt around for a while.  I dont think it happens when I'm sleeping, but when I'm just getting in bed.  And when I'm watching Grey's Anatomy.    So I found a remedy.  Putting a bar of soap under your sheets.  Yes, a Bar of soap.  So I tried it.  SO much better.  And last night, I was thinking, I think restless is coming back and I couldn't find the bar of soap under the sheets. Have to get another bar and tie it to the bed!
