Hi there, my first "long" Water Fast was 29 days...my second was 21 days, and others have been of shorter duration; but those two long ones meant a complete change of life. One of the biggest changes is the one my mind went through. Water Fasting meant a huge shift out of the paradigm of limited fear-based so-called "common sense" thinking.
I too, had previously believed (been brainwashed into accepting)that Water Fasting for more than three days or so, might kill a person! It seems funny now...
Read the R'd messages on the forum. Study the fasting lit that *proves* the value of water fasting. Do it wisely, and you'll do it well.
