Modalert 200 mg Pill works well for me and has been nothing short of a miracle. I don't feel fatigued during the day because of it alone. I felt drained and agitated all day before taking it. Not only does Modafinil help me manage stress better, but it also makes my intellect feel more active and lively. I can write and talk with greater grace now. In addition, I feel happier and more upbeat all around. Every day, I take 200 mg, and if I don't get enough sleep the night before, I take 150 mg.
