I tried the product for 90 days. I did not start it immediately as I was doing some traveling. It did not work for me consistently. About every other day I had to use either Magnesium or Miralax. I contacted the company to get my money back and they said since I did not use it right away and the timeline exceeded 90 days I can not get my money back. In good faith I used up the entire 3 bottles to give it the best shot, but I am being penalized for it. I feel this is a big scam.
