I don't know anyone who has to be on a liquid diet for 3 days. I had to eat low fiber foods for 3 days, then like a half a day of jello type stuff and a few hours of liquid, along with the horrible stuff that is supposed to make you "go." That stuff didn't work that great on me. The procedure itself was nothing, but unlike my DH, I was awake through the whole thing! Feeling no pain, but awake. The doc gave me a tour of my GI system on the screen. He actually asked me if I had done the prep, as it was hard for him to se, but I had drank every last bit of the stuff.
I came home and ordered take out Indian food.
