Query: Anything but "gentle"....

Oy. What a mistake it was to take this product! I chose it because it is advertised as being "gentle" but holy cow. I had excruciating stomach cramps and was writhing on the bathroom floor for an hour. Luckily I was at home and not in public! I mean, yes, it's effective, but expect diarrhea for several hours. I probably will never use this product again.
