Done !! So much help - I appreciate it.
I used to do Tai Chi a few years ago - I'll start that again for sure.
And on Friday night I usually have a couple of beers , chips, munchies etc.
So I'll change the beer for a health aid drink , increase the salty potato chips to 2 bags instead of 1 and eat more Avacado.
I'm told that Magnesium helps to lower cramp too.

Thanks guys !
