By improving alertness, drive, and attention, Artvigil 150mg (armodafinil) may have a subtle effect on personality in certain users, perhaps resulting in improved sociability and productivity. When using Artvigil 150, some people report feeling more self-assured, motivated, or intellectually alert. Others, however, can feel irritable, anxious, or emotionally blunted, particularly if they take it frequently or in large quantities. Although personality is not permanently changed, the short-term shifts in behavior and mood might be apparent. Because effects differ from person to person, responsible, recommended usage is crucial.
