I'm going for fasting bloodwork today for the neurologist. It's crazy when I don't have to fast, I often do it automatically, no problem. When I need to fast (for bloodwork, medical procedures), I find fasting very difficult and crave food. Only about an hour more to go. I can do it. Just hope I don't faint afterwards. I have a problem with that and then they make you stay there FOREVER until you start doing better.
