Artvigil 150mg which contains armodafinil does not directly make you "happier" in the sense of altering mood or producing euphoria. However, it may contribute to an improved sense of well-being indirectly by addressing excessive sleepiness and boosting mental clarity, energy, and productivity. These effects can lead to a greater ability to accomplish tasks, feel more in control, and reduce stress or frustration associated with fatigue, which might enhance overall mood for some individuals.

It's important to note that Artvigil is not an antidepressant or a mood stabilizer, and it is not intended to treat clinical depression or other mood disorders. Any improvement in mood is typically a secondary benefit of reduced fatigue and better mental performance. If persistent feelings of unhappiness or depression exist, it’s essential to consult a healthcare professional for appropriate treatment.
