Once you do take a sip, it takes only 10 minutes or so for the caffeine to kick in.
After as little as 10 minutes, the caffeine concentration in your blood reaches half the maximum concentration, which is enough to have an effect. The caffeine reaches maximum levels, making you most alert, after 45 minutes. Depending on how fast or slow your body's able to break down the drug, you could feel the effects of caffeine for 3 to 5 hours.
