bowel preparation
"I took one Dulcolax tablet at 9 pm. By 1 am, I was in severe gastric pain. The gastrointestinal cramping was very mild. I was sweating profusely, and in agony.  This side effect for me will stop me from ever taking it again for ANY reason.  The Excruciating pain almost landed me in the ER.  Has to take 4 Pepsid complete to get some relief."
