constipation
"I have taken this medication a few times & have had different experiences with it every time, from stabbing pains/cramping and nausea, to the last time with almost no symptoms at all. 
I think the main difference is in the preparation-I would never take more than one of these pills at a time (two was way too much). Furthermore, for minimal symptoms I take at around 7:00pm, drink four glasses of water (at least) and go to bed around 9:00pm. Wake up at 6:00am, and have a bit softer than normal BM. Make sure you are well hydrated when you take this product. With the good experience I had I hadn't ate since 6:00pm, and was well hydrated before bed."
