After years of bad middle-of-night bad leg cramps, daytime foot cramps (often while driving), hand cramps for no apparent reason, my MD prescribed Quinine Sulfate 260mg one a day at bedtime. I take just one after a bad night of pain and take no more till the next attack which may be 10 days later then I take another. Have no hand or foot pains either. It is a mild drug and has no side effects unless you heavy dose with it for example for malaria. Try it - it works. I also eat bananas on my wife's orders. Believe me this drug is 100% no pain for 6-10 days and I do not take it every night as prescribed.
