A bar of soap under the sheet is a natural remedy for not only night time leg cramps and restless leg syndrome, but also neck and back pain. Many use Ivory soap. Place the unwrapped bar under the fitted sheet to keep it from moving around. Most leg aches can be associated with dehydration and depletion of potassium. Gator-ade has sodium chloride, which replenishes lost potassium as well as rehydrates. Most bar soaps also contain sodium chloride. During sleep, it is absorbed thru the skin from the soap. A Florida man patented a cushion with compartments sewn into it to hold soaps. If you have leg aches, it would be easy enough to make a personal lap blanket using the info –> http://www.patentsencyclopedia.com/app/20120037164#b. When my legs cramp, I take a magnesium pill with a bottle of water and rub my leg with magnesium oil or magnesium lotion. If the magnesium oil makes you itch, switch to the lotion.
