bipolar disorde
"This is a great medicine.  Many people don't know about using it as an alternative to SSRIs for mood stabilization, depression and bipolar disorder. I've been on it for 1 year. The biggest benefits of this medicine is that it stabilizes my mood without feeling weird (fake, plastic, hyper) with very few side effects.  The sexual side effects and weight gain I experienced on Prozac, and the restlessness and irritability of Celexa and Welbutrin, just don't occur for me on this medicine.  
The drawback for me has been a narrowing of my emotional bandwidth.  I rarely feel spontaneous excitement or joy.  This may be partly because of life circumstances, but I'm certain that this medicine is also playing a role here. High anxiety, may not be related to this medicine."
