                                The half-life of caffeine, the active ingredient in mocha, is typically 4 to 6 hours for most healthy adults, meaning half the caffeine is still in your system after that time. This means a mocha can keep you awake far longer than the initial energy boost suggests, with the total effect depending on many individual factors.
