Constipation
"For all you &quot;horrible cramps, worst pain ever, bad drug&quot; people. You had a blocked Bowel. The directions warn using it with that, yet the only way I&#039;ve ever known I had a blocked bowel was when I was writhing in agony. So unless you have your own X-ray at home, I&#039;m not sure how one would know. 
Anyways, it&#039;s not the laxative to blame, it&#039;s your condition. Remember why you took it? People always confuse causality. &quot;I took X, then this happened. X is bad and at fault.&quot; It&#039;s more likely you would have gone through the same experience at a later time, and the laxative just brought it on sooner. I&#039;m pretty sure stimulant laxatives increase the pain and severity of cramps, which is why it&#039;s warned for. Yet a blocked bowel is hell. Been there."
