by this i just mean avoiding faint/dizzy spells, exercise and such. are electrolytes really the answer to all?
Pretty much, yes. I’ve undertaken long fasts before with no electrolytes and been fine, only taking them occasionally whenever I felt the need. Then it occurred to me that if I just took them every day regardless, I’d never have a “spell” in the first place. Snake Juice is cheap to make, and an ounce of prevention is worth a pound of cure, as they say.
