actually think body also requires sodium after fairly long water fast. This is main reason think people get such low blood pressure and have so much dizziness,faiting feelings on water fast. These problems I had on water went away when starting drinking on purpose high sodium clamato juice. I also took some potassium pills when started to get bad muscle cramps a sure sign of low potassium which can cause serious heart problems since heart is a muscle.
I think might even consider sodium pills if went on another long water fast. But think keep my Water Fasts to 14 mabye 21 days max from now on.
