Sometimes I wind up eating a little later than usual (say, an hour) because I'm busy drawing, but I could never forget to eat altogether. My metabolism is super fast, so if I don't get regular meals and snacks, I quickly start feeling really weak and ill until I eat again. It's a nightmare staying with my parents, because they don't have much I can snack on and eat later than I'm used to, so I start feeling dizzy an hour or two before dinner. I end up too hungry to draw.
