Well, at the risk of "TMI" (too much information), let me tell you that I just spent one of the most horrible nights I've had in a long time. No, it wasn't because of a colon cleanser, but I did have severe diarrhea most of the night, to the point where there was nothing left in my stomach at all, and if that's anything like what a colon cleanser does, then all I can say is "NO THANKS"!!
