I have the twitching, the tightenings, the pinches too.
I have been supplementing with liquid magnesium chloride, as well as Epsom Salt soaks and magnesium oil on skin after bath even! Still have leg cramps too. So,.....I've decided it is parasites, not minerals! I am going to the 'zapper' and 'Candex'. Later,....I'll go pharmaceutical if I must! These creepy, death-dealing THUGS are going to DIE!
Mark my words! :-)
