Hi
Have had a flexible and rigid gastroscopy, in the later case, throat sprayed first, and shot of intravenous Midazolam, shorter acting than Valium, only remember talking broken biscuits to the medic then waking up being wheeled out to the recovery area. You can have it with just the throat spray, me, coward with a yellow streak a mile wide down my back with things like this and I'm a nurse. Did give me nice colour pictures of the results though.
