Depression
"I&#039;ve suffered from chronic depression for over 20 years.  I&#039;ve been on a number of antidepressants and nothing has worked long term. I was put on this drug to ease the pain of a back injury and quite surprisingly and unexpectedly my depression symptoms disappeared completely. I became a happy productive individual overnight. Amazing!  Too bad it&#039;s an addictive opiate, and I imagine that, over time, the benefit would wane."
