bowel preparation
"In my prep for colon camera I had 2 before bed last night and 2 this morning.  Its 7pm now.
Needed toilet immediately this morning only once or twice, diarrhea city, but the morning pills kicked in at 4pm today and it was far harder to ignore this time.  More action than this morning.
Overall a few cramps here and there but I've been working in an office all day and not suffered much at all."
