Cramps - what helps?

[Cappuccinfortwo]

I have always been very susceptible to muscle cramps but now it's just ridiculous. Everything gives me cramp. Stretching arms over head in yoga? Agonising back cramp. Putting swimming cap on? Forehead cramp. GP just suggested eating bananas! Is there anything else I can do?

Increase salt to your diet, ironically cutting out salt also help, it's a fine line unfortunately
