Constipation
"If you are taking this product use it as A. Last resort and B. Take only one pill and if you do not get the desired effect then take another. 
I have severe constipation and when I take one pill I will pass the hard stool and a little more, but will not have diarrhea. 
If I take more than one then I will have severe cramping and I will have diarrhea after passing the hard stool. 
For me it takes anywhere from 3-6 hours to kick in and from the point where I start the bm it will last up to 5 hours. I usually clean out my bowel before that point but the cramps continue. If the pain is really bad I will actually take peptobismol or tums for my stomach pain."
