One word: WATER

I used to get leg cramps...not just the kind that involve the muscle behind the leg (like most people I know) but a muscle in front...and one that intertwines the calf. Immediate release from those cramps depend on quick action...and knowing which way to angle your leg for best results. Back of leg -- stand up and stretch by walking. Front of leg -- point toe sharply and grasp heel until pain is nearly gone. Intertwining -- difficult to determine, because the muscle is in several positions.

I've heard many remedies....calcium, magnesium, potassium, Vitamin E, sublingual quinine, some herbs, but the only consistent thing that worked for me was....lots and lots of WATER!!!!!!
