constipation
"This is the 3rd time ive taken dulcolax, and my experience has been awful, all 3 times!! Be ready to experience stomach burn to the maximum.  It is so very awful. I gave it 3 chances, but that was it. It feels like you are going to die, the cramps and burning, not worth it. I am allergic to Miralax, so i will switch to a natural remedy, or maybe stay constipated, before i take this horrible pill again. I mean, it freaking works, but the stomach discomfort is insane... never again!"
