I have been on this program for over a month now. Was 28 pounds overweight, have lost 8 pounds so far, but I have been incorporating over an hour of exercise 6 days a week. At first I was very sick to my stomach, on the first cleanse day, which was easy, I experienced accelerated heart rate and actually felt alarmed. I followed it to the letter and the next day... GAINED 2 pounds!! I wanted to stay the course, so in time started to feel less sick to my stomach. The weight loss seems very slow, and now my hair is starting to break off and fall out!! My husband had to stop using the shakes as he was having excruciating pain starting in his back and traveling around the left side and up to his abdominal area... I just am writing in here to see if anyone else has had these problems!
