I would like to know a good pill without causing symptoms of nervousness for bipolar?

I am bipolar and I am taking risperidone and biperideno. Its making nervous taking risperidone. I think biperideno is not making me nervous but risperidone yeah. I saw the side effects and one of them is nervousness. Does anyone know what other pill is good to take for bipolar without causing nervousness on me. Thank [...] http://bit.ly/oGWVL5
