constipation
"My girlfriend struggles with IBS-C (constipation) and after trying milk of magnesia and a high fiber diet for 2 days with no success, turned to Dulcolax's version of this drug. She took 2 pills at 10pm and at 5am she woke me up saying she felt like she was dying with cold sweats, nausea, and no bowel movement. Her cramps lasted a little over a  hour (till they fully subsided). We won't be going with this drug anymore which barely caused a bowel movement the next day. Definitely not for the faint of heart."
