Is it just ME..???
for cramps, I sometimes take Magnesium, Potassium, Zinc, and various vitamins like D and K. I'm 5-9 and 200, a lil thick around the middle, nothing another pump or two on the jack-handle cannot handle.
Bananas are good, as are certain nuts, but, I bet that you probably already went to a nutritionist. I'm a Believer in the Risen Son, so I tap into the supernatural.
