It really works. But if you're like me, you'll just be postponing the point of no return. Besides, you'll have to eat like a pig or a lion, which isn't very pleasant for someone who isn't used to such excesses.
The problem is that there won't always be a feast. In many social situations, there will only be drinks. Then you'll be someone who still drinks... And how can you refuse to have just one with friends? So, when you realize it, your friends have already disappeared, and you're in another bar, among strangers, taking every possible risks... getting into trouble.
