I've used it. I haven't had any problems with it. You need to keep your fat gram to a certain level for each meal. If you, you are fine. If you go way over, It will cause the bowel problems. It teaches you how to eat correctly.
The effects can take 24-48 hours. If you are going to have a big fat meal...you can either not take the pill and be ok, or take it and you may have problems afterwards. The choice is yours.
