I've never had a colonoscopy yet, But I know I should have one soon (50's here). I've heard the stories of sedation during the procedure and would rather not experience that. I'd much rather go without any sedation. From what I've read, doctors normally only perform the colonoscopy with sedation. Can they also perform without sedation? If so, how do you recommend I ask that no sedation be given? What are your experiences without sedation?
