title_body: Recommended time to finish a cup of coffee for the best caffeine surge?
upvoted_answer: Physiologically, as soon as substances enter the body, they are being processed, entering your system and subsequently removed from it. By that logic, you will experience the greatest net effect of the caffeine content of your cup of coffee by finishing it in the shortest amount of time possible. This is assuming that your definition of 'best kick' is indeed attempting to feel the most potent effects of the caffeine available in your cup.
