Unlike most of you guys I never help myself to anything after I've had my dinner until the next day and even then I don't have breakfast early. I've conditioned myself that way. I've never either felt an urge to wolf down something late at night nor felt any hunger even if I didn't eat much the previous evening. In fact, come to think of it, I'm starting to develop an aversion towards food.
I must have late night supper everyday because if I don't I'll have gastric. I get hungry very easily all the time so I tend to have a large meal, not exactly a "snack" to be honest. Usually, either I'll cook pasta with some seasonings or sandwiches. For cost saving I don't buy snacks from convenience stores.
