constipation
"I used to take dulcolax with no problems, but today I took one tablet, passed stool  3 hours after with no cramps at all. But after 6 hours I had this sudden left abdominal pain, 7/10! I stayed on the toilet too long just passing gas and a bowel movement (slight), until I started feeling nauseus and felt cold and clammy. I washed up and just collapsed on my bed. Felt better After taking buscopan for the cramps. Never again!"
