I also have been given Versed by a doctor and not enough to cover the most traumatic part of the procedure (a widening of my esophagus that required me to be conscious and shift positions when necessary). I vividly remember reaching my hand out, 5 fingers stretched wide, to try to grab and kill the doctor. I remember a needle was then injected into the back of that hand and then I saw some lucky charms floating in front of me and that was that (they had to knock me out). True I've forgotten most of the events of that day, even after leaving the hospital, but it is my opinion that the most traumatic moments still register and the drug is only meant to minimize trauma. It would definitely not make someone forget full-blown torture, especially at the dosage required to have the person respond in a meaningful way to interrogation.
