Users usually report increased wakefulness for 10 to 12 hours after taking Modalert 200, which includes modafinil. Because the drug is intended to enhance cognitive function and alertness, it works best when you need to remain up late to complete activities or go to work. But, if you take the stimulant effects later in the day, it might be hard to fall asleep, so be sure to adjust your schedule properly. To get the most out of this window, you should ideally try to remain up while keeping in mind your general sleep requirements and health.
