I'm on 2mg of Klonopin a day, but I use it as an anti-anxiety. Before I was diagnosed with BP, and was only taking that medication, it had very negative effects. Combined with actual mood stabilizers though, it works great.
Klonopin can work as a mood stabilizer although generally its an anti-anxiety medication. Prozac is an anti-depressent. Seroquel at that dose would be effective for sleep but not enough to have a mood stabilization effect. Ask your psychiatrist if you want to know more.
