The notion that the creative muse can be found in booze is as old as the ancient Greek myths. Literary genius, unlocked by alcohol, is part of the legend of Tennessee Williams, F Scott Fitzgerald, Dorothy Parker, Dylan Thomas and countless other sodden successes. Many of whom we imagine at the typewriter in a sepia-toned, romantic haze, rather than embarrassing themselves, sloppy, or shaking with DTs. 'Why do writers drink?' wondered Blake Morrison -- himself a poet – author and professor of creative and life writing at Goldsmiths, University of London. He’s also a fellow of the Royal Society of Literature, who wrote about why …and how…writers drink for The Guardian.
