My NT boyfriend gets in a bad mood when he's hungry. When he gets in from work he sometimes comes in like a bull in a china shop; barges everything and everyone out of his way, gets impatient, and won't be his normal self until he has eaten. It's worse when we're out, because when we go into restaurants he gets frustrated with me if I have never been there before and unsure of what to do. He doesn't get frustrated in a nasty or frightening way, just gets impatient and I can tell that it's best to just be quiet until he has eaten. But when he gets impatient due to being hungry, it gets me into a bit of a fluster, which causes confusion and object-blindness for me, which gets him more impatient, and things are just better once we have sat down and eating.
