Modafinil vs. armodifinil for wakefulness and focus?
I'm researching eugeroics and keep seeing modafinil and armodafinil mentioned for wakefulness and daytime alertness. For people who have actually discussed or used these under appropriate medical guidance, how do you compare their effects, duration, and practical differences? I’m particularly interested in experiences around concentration, mental fatigue, and staying alert during demanding work not medical advice or dosing recommendations.
