constipation
"I was violently sick from taking this. Sure, it relieved the constipation but at one point I was debating whether I need 911. 
Product: Bisacodyl USP 5 mg, marketed as CVS Brand Women's Gentle Laxative. I am a middle-aged female, about 135lbs, no health probs.
Yesterday I took one tablet in the afternoon. At 8 PM I felt nauseous, some abdominal rumbling. 8:30PM I vomited so hard that I actually wet myself. That was followed by wave after wave of violent abdominal pain. I was sweating so heavily that I stripped off all of my clothes, and so weak that I just laid on the bathroom floor in misery. I vomited again, then had diarrhea. Again at midnight. Again at 2AM. Finally recovered around 5AM. It was a nightmare and I would never take it again"
