depression
"This medicine helped my daughter like no other we have tried, and we've tried *a lot* over the past 8 years.  She has bipolar II and the depression with that has been very treatment resistant.  This is the first medicine I've seen her on where she is herself.  The others have either done nothing, induced mania, or made her into a non-feeling zombie.  The only downside is the weight gain.  I just hope it continues to work over more time."
