bipolar disorde
"So far the best medication for bipolar disorder I've taken.  I started out successfully at 20mg for a year.  Then I developed twitching on the left side of my body.  My doctor reduced my dosage to 2 mg a day and put me on Artane.   I am glad I found this medicine because I don't have to take it daily and I no longer feel as if I'm going insane.  Helpful, but you really need to pay attention to the way your body handles it. My twitching has gone away thankfully."
