constipation
"I was constipated for a few days so I decided to give these a shot...never again. The most severe stomach cramps I've ever had in my life, and they lasted for two hours. Two hours of sweating profusely, lying on the bathroom floor crying from the pain, considering how embarrassing an ER visit would be at 3 am because of Dulcolax cramps. It's like period cramps but a hundred times worse. When the medicine finally did its job, it produced staggered streams of hot lava for the remainder of the night. Needless to say, the intense pain wasn't worth the small, painful BM."
