How long does 200mg of modalert keep you awake?

For most people, Modalert 200mg keeps you awake and attentive for ten to twelve hours. Typically, the effects begin in 30 to 60 minutes, peak in 2 to 6 hours, and then progressively diminish. However, because of its extended half-life (about 12 to 15 hours), residues are still present in your body and might interfere with your ability to sleep later. Depending on their metabolism and tolerance, some people may experience even longer periods of alertness. Although Modalert 200mg helps lessen drowsiness in diseases like narcolepsy, it doesn’t take the place of adequate sleep, and taking it too late might result in insomnia or irregular sleep patterns.
