Question 20 of 20 Correct

What time of day should you stop having caffeine for a good night's sleep?

The correct answer is: Stop drinking caffeinated beverages about eight hours before bedtime.

If you cannot go cold turkey on the caffeine in the afternoon, then switch to drinks with less caffeine, such as teas.
