bipolar disorde
"Works like a charm.  It was prescribed for me for Bipolar I disorder (as part of my cocktail of meds), especially for symptoms involving lack of sleep.  I have been struggling with sleep problems for so many years, and this works great for me at 50 mg.  It even helps with depression and anxiety temporarily.  I feel a lot calmer, which is definitely needed for me, especially at night.  It helps with racing thoughts and voices as well.  No more "noise" in my head at night for most part."
