I quit Fasting because of the leg weakness, however magnesium supp on re-feeding helped it. I messed up the fast by drinking water high in calcium and thus I created a magnesium deficiency in my Fasting body; So don't make my mistake if you fast; anyway if I do it again I will tell you than we can me Fasting buddies ? :-)
I just need to know how long to wait to prevent starvation modus between fasts;
