Answer 1

uhmmmm.... I dont find much of an effect, i guess probably a couple hours....... but the good news is, once it starts to wear off...... poor another cup :-)

why do you ask?

Answer 2

The precise amount of caffeine necessary to produce effects varies from person to person depending on body size and degree of tolerance to caffeine. It takes less than an hour for caffeine to begin affecting the body and a mild dose wears off in three to four hours.
