It's nothing compared to a colonoscopy if you have ever had that before. They just make you drink this white pasty substance and ex-ray the substance going through your upper GI tract. I was only there for about half an hour to forty-fice minutes. It depends how fast the substance goes through you. Don't worry you will be fine. It really isn't that bad. It will be over before you know it. Just be very careful what you eat afterwards for a couple of days the substance aggravates the GI tract. So only eat safe food and drinks lots of water so that the substance leaves your body quickly.
