Apple Cider Vinegar in water in the a.m. THE AMISH have a product that works also for me.Caleb Treez Organic Farm, I take two ounces of this when I get the charley horse, it STOPS IT COLD in less than a minute. THE AMISH use it for their aches and pains after farming all day, it does work. I hopped around in severe pain and even went to the ER once and they did nothing. THE CHARLEY HORSES IN THE BACK OF MY LEGS WAS SCREAMINGLY PAINFUL. You will have to do some stretching exercises off the internet to keep the CHARLEY off....Margaret O'Brien....sufferer of NEUROLOGY in the legs.....You can order this on line...I always get two at a time and keep them by my bed...M.
