Excessive eating

I had lunch today with some friends at an all-you-can-eat Japanese food restaurant.  I ate so much that I feel like I committed a deadly sin - gluttony.  We ate at 'Matsuda', a restaurant in a plaza at the corner of Middlefield and Steeles.  For a decent price $14, I definitely over-ate.  It's been well over 5 hours since we had lunch, my stomach is still bloated and I feel nauseous.
Whenever I go to an AYCE restaurant, my friends and I have a bad habit of saving an empty stomach.  It's a bad habit because when we order, we feel so hungry that we order more than we can actually eat.

Does that happen to you? Ordering more than you can eat?
