Very timely info - I've been kinda wondering about this...
Three-day fasts are talked about in the bible, too. They're called "fasts", not "water-only fasts"...hmm.
Reason I've been wondering, is this. I still, on occasion, get horrible edema in my calves and ankles and feet. (I have coined the term, 'pedicankles'. lol. The nights I've gone to bed withOUT taking water - more often than not - I awaken to NO edema.
Which is something that I always thought was really weird since edema is also related to lack of hydration.
I must try this. However, I did have a little sugar today, so better wait another 24 hours.
