Overview
Modafinil is widely regarded as one of the most effective wakefulness-promoting agents available. It supports prolonged periods of cognitive performance without the typical crash associated with traditional stimulants. While highly effective, it is prescription-only in many regions and should be used responsibly due to potential side effects and individual variability in response.
