When they put the IV in me, it was such an incredible state of wellbeing but with energy. In my adult life, I have never felt like that on my own. And then, Paula, Dr. Mestayer, and the nurses would say, "How is the craving?" I said, "I haven't had one inkling of a craving whatsoever." It vanished in 20 minutes of the first IV. So I'm telling you that it worked immediately!
