of course, my n=1

when i started atkins i would get cramps in the back of my lower leg between my knee and ankle. adding salt fixed that and stopped the cramps (first msg bullion cubes (didn't know), then salt under the tongue, then found some msg-free bullion).

ff to today, months later, i don't supplement with salt anymore and don't get the cramps either. when riding my bike though, i make it a point to add salt, and ^ that advice should do the trick i'd say.
