Were you informed when you were given Versed?

I was quite well-informed in the two procedures I've had (a colonoscopy and an upper endoscopy), but I know that some sites out there describe the experiences of folks who have been given Versed during a procedure without having been told first. So, if you've had a colonoscopy before, were you given Versed (or any amnesic anesthesia) and, if you were, were you informed about it and it's side-effects beforehand?
