Yup ... Same here on leg cramps and they can be intense. What helps me appears to be related to how much water I am drinking. As soon as I increase my consumption levels it helps a lot. I find missing my daily B & D vitamins for a 2 days also appears to generate cramps.
One nurse suggested that I drink tonic water which she noted helps a lot of runners avoid and stop leg cramps. Dont know if any of that info helps. J ust passing along my personal experiences for what ever value they are worth.
