Nuvigil
"My psychiatrist initially prescribed Nuvigil to enable me to be alert and awake during the day.  I suffer from bad insomnia and I'm being treated for major depressive disorder and post traumatic stress disorder.  I'd taken Provigil in the past and it seemed to help with depression.  Yesterday I overslept and decided not to take my Provigil fearing it would keep me awake even longer than usual.  That was a huge mistake, I became horribly, morbidly, depressed.  I didn't make that mistake this morning, I took my Nuvigil as usual and my (worse than usual) depression is gone.  I haven't experienced any side effects but I wish Nuvigil would enable me to lose weight like it does many people.  I was on Abilify for a few months and gained several lbs."
