They have a new solution you can now take, without all of the gallon of stuff.Don’t sweat it you won’t know a thing about it. My first one the Doctor let stay awake and watch the entire procedure then he gave me a C-D with the procedure to take home, for some reason most people don’t want to watch, but it was interesting.
I was out for mine, but they gave me pictures. I don’t think I would care if I was awake, and might like to watch it on video. I don’t think I want to FEEL it tho! LOL I had a barium done years ago, not very pleasant!
