All told, Withnail drinks roughly 9 1/2 glasses of red wine, 1 pint of cider, 1 shot of lighter fluid, 2 1/2 shots of gin, 6 glasses of sherry, 13 whiskeys and 1/2 a pint of ale. Seeing as the whiskey alone would be more than enough to nessecitate a trip to hospital for most people, it is only the most hardened fans of Withnail & I who can keep pace for the entire film.
