constipation
"I have taken the laxative in the past, usually in the evening.  I would wake up and have bad abdominal pain and several bouts of diarrhea until the next morning. This was with only taking one pill. I reluctantly took one last night but felt bound up and uncomfortable. I woke up at 1am with terrible stomach pain and hot flashes. I had to take off my clothes and lay on the coolest floor I could find. It was horrible. Then I vomited about 5 times and felt some relief. Shortly after I had a normal bowel movement then went back to bed with the chills. I sleep well after that and woke up feeling fine. I threw the box of dulcolax in the garbage..never again! Not worth going through that agony."
