As I think most people are until some wake-up call comes along and shows you just how "blah" you've been feeling for so long! It happens so gradually, too, so it's impossible to notice.

Never done a fast myself, might have to try one on for size here in Mexico since there's so much fresh-squeezed juice for cheap. :)
