it's a salt deficiency. it's very good for you, if it's free from heavy metals.   you might have an underlying condition in which you don't regulate electrolytes properly. or you might just exercise/sweat a lot and need to replace it. if you are getting dizzy or lightheaded you need salt.  you might like to try redmond realsalt, it's tested for heavy metals and probably the tastiest salt i've ever had.    > also, rock salt causes brain damage wat? only if it's contaminated with lead.
