bowel preparation
"Having crohn's, I never suffer from constipation, ever.  I took 2 dulcolax Wed at midnight as directed for an endoscopy on Friday. Felt lots of gas discomfort within 25 mins. Impossible to sleep! Really painful cramps started by 2:15 am. Turned to extreme cramps every 10-12 minutes.  Like hard labour.  Severe diarrhea and vomiting for the next 3 hours, nearly passing out thinking I might die with forehead neck & inside elbow crease sweats for hours. By morning I am now passing blood with diarrhea. Cramps 20-30 mins apart. My crohns WAS very good for months. I don't think it's safe for 'some' like 'ME' to take this medication.  Pico-Salax should be sufficient for those whose bowels empty very quickly due to faster digestion."
