This was despite his continuing large daily intake of alcohol. Harold Nicolson recalls a friend coming away from lunch with Churchill “rather shocked by . . . the immense amount of port and brandy he consumed.” On a typical day, according to his aide Sir Ian Jacob, Churchill drank champagne and brandy with lunch, then, after his afternoon nap, had two or three glasses of whisky and soda, then champagne and brandy with dinner, followed by more whisky and soda. Jacob noted that he also sometimes accompanied his breakfast with white wine.
