A change in the mood is the most precious thing that alcohol achieves for mankind, … A cheerful mood, …reduces the inhibiting forces, criticism among them, and makes accessible once again sources of pleasure which were under the weight of suppression. …Under the influence of alcohol the grown man once more becomes a child, who finds pleasure in having the course of his thoughts freely at his disposal without paying regard to the compulsion of logic.
Freud, S. (1905) St. Ed., VIII, Page 127

Consider, for example, the relation of a drinker to wine. Is it not true that wine always provides the drinker with the same toxic satisfaction, which in poetry has always been compared to erotic satisfaction ... If we listen to what our great alcoholics, such as Bocklin, say about their relation to wine, it sounds like the most perfect harmony, a model of a happy marriage.
