Waking Up at 4:00 AM for a Colonoscopy

Honestly, in addition to the process itself… the administration of this drug was also fairly unsettling to me. I heard stories of people emerging from this having said or blurted out all manner of crazy things.
Part of me wondered: what would I say? Horrible things about what I thought of others? Would I blurt out statements that would reveal me for the horrible person I am, deep down? Would something happen where I would lose all of my memories, and not just the ones during the procedure.
