The British prime minister kept to a similar daily routine no matter what happened. In the book "Daily Rituals: How Artists Work," author Mason Currey recorded Churchill's schedule:
At 5 p.m., the prime minister would drink another weak whisky and soda before taking a nap for an hour and a half. Churchill said this siesta, or short nap, allowed him to work for 1.5 days every 24 hours. When he woke, he bathed and got ready for dinner.
At 8 p.m., Churchill would have dinner, which was often followed by drinks and cigars well past midnight.
Due to his irregular sleep schedule, Churchill was said to hold War Cabinet meetings in his bath.
