In order to write at a high level of competence you need a comprehensive vocabulary, a keen sense of overall structure, and an inner beat or cadence. Your senses must be razor-sharp. Alcohol blunts those senses even as it releases self-restraint. Therefore many writers feel they are getting down to the real story after a belt or two, little realizing they are damaging their ability to tell the real story.
