A daytime-alertness stack pairing modafinil with NAC — for focus and wakefulness on demanding days.
Modafinil is a wakefulness-promoting agent (eugeroic) used for alertness and focus without the crash profile of classic stimulants — the anchor for a daytime-performance goal. NAC is added as an antioxidant/cognitive support.
Modafinil is a prescription medicine (for narcolepsy and shift-work disorder); off-label cognitive use is common but carries dependence and tolerance considerations. This is an alertness stack, the daytime counterpart to the sleep stack — and it sits firmly in 'use responsibly, ideally with a prescriber' territory.
