Depression
"My psychiatrist initially prescribed Nuvigil to enable me to be alert and awake during the day.  I suffer from bad insomnia and I&#039;m being treated for major depressive disorder and post traumatic stress disorder.  I&#039;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&#039;t make that mistake this morning, I took my Nuvigil as usual and my (worse than usual) depression is gone.  I haven&#039;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."
