"Caffeine Blues: Wake Up to the Hidden Dangers of America's #1 Drug" (found on amazon dot com) says it takes about 2 weeks to get all caffeine out of our system, and recommends ways to very gradually reduce consumption of caffeine until we are completely caffeine free, bringing us more restful sleep quality and greater natural energy during the day.
