Drinking and driving don't mix. We all know that.
But drinking and writing, well. . . . there have been numerous examples of excellent writing by writers that indulge.
I seem to recall that D.H. Lawrence had a fondness for liquors made with Fennel.
Faulkner's drink of choice was Julep. (Photo below of Faulkner's metal cup on exhibit at his house in Oxford, Mississippi, posted by Paris Review on FB)
Fitzgerald, well I suppose he'd guzzle down just about anything. Perhaps more than usual amounts if in the company of Hemingway (cf. some of his Parisian bar haunts: Fouquets, Closerie des Lilas, Le Select...).
Olivia Laing has just written a book on this subject: The Trip to Echo Spring: On Writers and Drinking (Picador, 2013).
