I have a friend's wedding and I'm going to visit my family in a month. I'm backed into a corner and I HAVE to fast, or be humiliated. So...I'm on day 5 of my water fast and still going strong. In 12 days I lost 21 lb. on my last fast, so I'm sure you can expect similar results since we are about the same starting weights. I've read to only drink distilled water---I get this from my grocery store. And make sure you do enemas regularly or a salt water flush----read about it on the forums. I had to stop that 12 day water fast because I wasn't drinking enough water (at least my body weight in ounces), or doing the right kind of enema (I used fleet enemas and they took my electrolytes with them)----and I was doing well up to that point. You CAN make a dent in your weight. Get past the first 3 days and you'll feel like a new person after that. Take care and let me know how things go!
