The responsible use of caffeine can make us more alert and energetic, and it can improve our concentration and coordination.
The proper use ... watchful/nimble/vigilant ...

Hi,
The second of the above is how I understand the first? Correct me if I am wrong. Thanks.

    Yes, "responsible" might be interpreted as proper, careful, judicious, measured, etc.
    I wouldn't say that alert is in this situation equivalent to watchful or vigilant and especially not to nimble. Alert can refer to more than being aware of our surroundings; it can also mean that we are more mentally agile, more mindful and focused.
