Modafinil reduces sleepiness due to narcolepsy, shift work or various sleep disorders. Modafinil and Armodafinil are also used to help you stay awake during work hours if you have a work schedule that keeps you from having a regular sleep routine (shift work sleep disorder). Common off-label uses are college and university students who take Modafinil to focus better on their studies, as well as overall cognitive enhancement. Professionals often take Modafinil for the same reasons, with their goals of increased work productivity and creativeness being key factors.
