Sounds like me, except Vyvanse instead of Modafinol. Bupropion was the magic key. I thought my Vyvanse just wasn't working anymore.

Turns out I was just super depressed. Since switching meds I've lost a lot of weight because I don't have food cravings as much.

The way I think of it... Vyvanse keeps me focused when I get to work, but without Bupropion just getting out bed sometimes seems daunting. One gets me to start my day, the other keeps me focused when I do.
