A colonoscopy is typically done when inflammatory bowel disease is suspected. IBS can sometimes be a diagnosis of exclusion - once everything else is eliminated from the list of possible problems, you're left with IBS.
You can search this forum for information about colonoscopies. There are lots of good BTDT stories. You should be able to do the prep while taking an anti-anxiety med. For the procedure you are under sedation so you will not feel anything.
