The capsule has redundancy measures to keep you from falling asleep in it. It'll pump SO MUCH caffeine into you. However, there are limits to the human body, such that at least once during every 24 hour period, you'll get at least 30 minutes or so of sleep. CONCORD mandates that this time period occurs every day between roughly 11:00 and 11:30 to keep terrible things from happening.
