I'm due to have a colonoscopy and biopsies soon and I'll be having sedation. My question is about how the sedative affects your mind during the procedure? I'm worried I'll start telling the doctors all my secrets or something or start swearing like a fishwife or even blabber on about my fear of dying (don't know if it's inflammatory bowel disease or something even worse as yet). Can anybody tell me do you stay totally compos mentis throughout?
