It's no secret that some notable authors were also notable imbibers. I'm not going to name any names, but I know a fair number of people who prefer the Hemingway approach to writing. While I can't recommend that route personally, I am interested to know that Oscar Wilde was a fan of absinthe. Whether it's whiskey (neat, please) or a very dry martini, Flavorwire has rounded up a nice gallery of famous authors' favorite drinks. Link
Alcohol is easily the most socially-destructive habit enjoyed by the most people. And when a vice has such a large following, it is very hard to discourage. But I do know some who overcame the glorification of alcholism.
