constipation
"I tend to suffer regular bouts of constipation and have found that Miralax and other powder-based laxatives have had little effect.  I decided to give Dulcolax a shot while on a trip as it was very uncomfortable to be so bloated while doing some strenuous activities.  I took three tablets (I'm 6'5" 250 lbs and usually take max dose) on Friday at 7PM.  Between HORRIBLE cramps, chills, cold sweets, weakness, and constant runs, I felt like I had taken the pill-form of food poisoning.  It is now Monday at 11 AM and I am still unable to eat anything without it going straight through me.  This is not worth it, and Dulcolax should not be advising people to EVER take three of these.  Awful experience."
