Yup, I have. I've fasted for almost 2 full days and felt fine. When I finished my fast I had some water and small snacks and then later had a larger meal—my throat is usually a bit dry and it can hurt jumping into a big meal. I find when I fast that my mind is more alert and I'm more efficient too. I've grown up as a Mormon though so since I was a teenager I had usually fasted at least once a month for two meals so maybe I'm more used to it than most people would be. Also, I'm naturally quite thin so that probably has something to do with it too.
