Important Nuances
Armodafinil is the R-enantiomer of modafinil. It has a slightly longer half-life and some users find it more consistent through the afternoon compared to modafinil. Take even earlier (6–7 AM) to avoid sleep interference.
Frequently Asked Questions
Is armodafinil's half-life longer than modafinil?
Yes — armodafinil (R-modafinil) has a slightly longer half-life (13–16 hrs) compared to racemic modafinil (12–15 hrs). Many users also find it provides a smoother, more sustained wakefulness vs. the more 'peak and dip' profile of modafinil.
