constipation
"If you need to go to the bathroom and are constipated, this laxative is EXTREMELY effective.  But be warned, the side effects are terrible.

Thinking this would be like most other laxatives, I expected to sleep through the night and wake up to go to the bathroom.  Instead, I was up at 3 am uncontrollably vomiting (It wasn't even food, just stomach acid).  There was an intense burning in my stomach that would come in waves.  I had chills, shaking, felt lightheaded, and couldn't sleep.  I spent the next day on the toilet pooping straight up liquid.  I took one pill a few days later and experienced the same effect"
