Bisacodyl
"First time using this. Doctor recommended I take the three pills because I really needed it..

I took three pills yesterday around lunch. It is now 9pm the following night and I am STILL in severe pain. I have had severe stomach cramps and chills since noon yesterday  And I feel like they are getting worse. I have had two natural childbirths with preeclampsia and having to be induced. I know pain. This is not as bad as child birth but it is close. I will NEVER take these again. I only wish I hadn't waited until I was sick to research side effects of this drug. 

I hope this ends soon because I am useless right now. Thank goodness its a 3 day weekend and my husband is here to help take care of our children. Pain is excruciating"
