Probably: Caffeine is a potent drug used to promote wakefulness. Although the half life is 3-12 hours in most people, it is likely that you could prevent sleep onset at bedtime as there will be caffeine around at 4 hours after consumption. Best to avoid caffeine in the evening if getting to sleep is a concern.
