bipolar disorde
"I took Nuvigil for the first time and I found myself less tired and more active than ever. I have severe depression and stay tired a lot. For years, I haven't been myself as for being active I was an athlete for half my life and I knew what being in shape felt like, but with aging I fell into depression and bipolar. Still too early to say, but Nuvigil made a positive difference for at least one day of my life."
