Colonoscopy? That's the one where they make you drink the Go-Lightly (that actually makes you go-heavily, LOL), isn't it? My W thought (with her trip to the ER yesterday for abdominal pain) that the docs might want her to have one, but she was able to avoid it. Well, we'll certainly be hoping and praying for the best result from that. In any case, not knowing what the problem is must be stressful in itself. Have you scheduled it yet?
