Hi! I know how frustrating it can be when this happens. Maybe your body just needs time to adjust to the rapid weight loss. Or, something else may be going on. Could it be "that time of the month"? When I was juice fasting, this happened to me. I gained 3 pounds. Then I realized what it was. It dropped back off a few days later, and took a few of its friends (about 6 pounds total).
12 Days is GREAT! How much have you lost so far? Are you feeling hungry yet?
You're to be commended for doing so well for such a long time! Please keep us posted.
