bowel preparation
"A first time user, I took two little orange pills and experienced the worst abdominal pain, ever. I once terminated a colonoscopy that was underway on me with no anesthesia (long story), and this pain equaled that. My thanks to you fellow website contributors who gave me confidence to avoid the emergency room after searching on "Dulcolax cramps." The extreme pain lasted at least an hour; it subsided gradually over the next 5 hours. Have someone aware of what you're going through, and be safe about possibly passing out. I did not pass out.
