I had the enteroclysis done at the end of Sept. I was a bit nervous before the test because I heard that they used the NG Tube. I didn't have to do any prepping at home before the test. The morning of the test while on the xray table, I inhaled some medication to numb my throat. They then gave me a mild sedative to take the edge off, as the tech put it. They injected the contrast through the NG Tube so I didn't have to drink any of it. I didn't feel any of it because I really didn't know what was going on. The test was nothing like I had been fretting about. It's not bad at all.
