have a bellyful (of something)

1. To have as much (food) as one wants or is able to eat. A: "Would you like seconds?" B: "No, thank you, I've had a bellyful."

2. To have more (of something) than one can or is willing to tolerate or endure. You're looking for trouble, huh? Well mister, you're about to have a bellyful! I've had a bellyful of my parents' criticism over my college applications.
