Flapjack worked wonders for me in the early days. You can add fruit to flapjack too. (I did get a few "you're going to eat all of that?" comments too, but I was hungry!)

Last night I ended up eating a whole tube of salt and vinegar pringles and drinking a litre of apple juice as a "snack" before DH came home. But I figure I don't eat loads and loads, so I'm allowed the occasional pig-out!
