Hungrier

Have you ever been hungrier than you should
At the time, so you eat some little snack and then call it good,
'Cause you're also worried you might get too full,
But you can't; even your hunger is hungry too,
So you're pregnant for a minute, eating for yourself plus two,
So that whatever you put in gets totally smothered?

I've always been like that, one way or another.
