I am sometimes awakened in the middle of the night with excruciating leg cramps. Some remedies that I have personally tried that have worked for me are getting out of bed and walking, sipping some liquid minerals added to water, also drinking pickle juice. Hyland’s Leg Cramp Pills available at pharmacies, Walmart and Amazon are said to be an effective remedy. Believe it or not, some people say just drinking a glass of water works for them. Others swear by eating a banana each day, or adding supplements such as magnesium, potassium and zinc. I would check with a doctor on this though, as it is possible to take too much and experience ill side effects. This video is very helpful and gives a number of causes and helpful treatments.
