I was so sick with my first and so far (5 months) with my second that I can't eat anything, so my advice isn't from experience! But I would eat as often as you are hungry and try to eat the healthiest version of what you crave. For example, if you are dying for chocolate, see if you can find a granola bar that might have fruit, nuts and chocolate. And protein helps you feel full for longer, try filling up on that first.
