Calf cramps during waking up process in mornings

I have a theory that all the sweating from heat flashes and all the water I drink to counter act the water loss is depleting minerals. I've been taking calcium/magnesium, kelp tablets for potassium (bananas work too) and the cramping has stopped. Also salty olives....basically electrolytes.

I've just recently completed a one week voluntary cut back in water intake while continuing my usual workouts (I weight train). The issue of dehydration and leg cramps came up on another thread where I stated that I was convinced squats and lunges have obliterated the gruesome leg and foot spasms. Others wondered if it was the extra water I drank in the gym. Today was day 7 on half water and I haven't had any return of the cramps. In the past if I took a break from the gym the cramps would come roaring back with a vengeance, even if I drank the same amount of water, so I'm still convinced it's the exercise. Weight bearing leg exercise is worth a shot IMHO. It's been the only thing that's stopped my feet from involuntarily turning into agonized pretzels or watching my calf muscle turn around leaving me limping for a week.
