Contrary to popular belief, alcohol does not improve one's mood. It just enhances the mood you're already in. If you were in a good mood before drinking, you will become ecstatic and boisterous after a few drinks. If you were in a bad mood before drinking, you will be morose and depressed after a few drinks, unless you drink so much that you pass out and become unconscious. You won't feel a thing then but that only lasts til you wake up with a bad hangover feeling worse than before.
