Sujaya: Thank you for the info on Powerade Zero and Klonopin. If the salt cure stops working I'll look into them further. The salt is actually working at lightening speed. Earlier this week I took some at bedtime when the first twinge hit and no cramp happened. Last night the same thing. I got really bad twinges in my foot (the toes curling type) and had to walk around to ease them. This ALWAYS means that I'm in for a bad night with spasms up through the calf. But I got a bowl of salt from the kitchen and kept dipping my finger in it until I couldn't stand the taste any more. Guess what? No cramp. I'm kind of shocked by it.
