I dont want to assume what everyone means here when you guys refer to "C" and "D" My guess is "C" means constipation and "D" means diarreah. Are there any other types for I.B.S.? While im asking, I've seen lots of abbreveations used on the boards. Since I can only type with one finger, could someone explain what the most common abbr. mean? My finger would appreciate it. Thanks!
