The best time to drink coffee is actually between 10-12 noon and the next window is from 2-5pm. Drinking coffee at these times does not interfere with the natural energy cycle your body produces. And by waiting for the ideal times you also minimize building up a "tolerance" to the caffeine. Read the story to see how important cortisol is to the process.
