I too am BPII. The insomnia was the worst symptom and it had a negative synergistic effect in worsening the other symptoms. I would go for days with no sleep or at best an hour or two of non-restorative sleep. Then I was prescribed Seroquel. The first night I took the minimum 25mg dose and slept for 14 straight hours. I have since discontinued the Seroquel because it was a bit too effective - leaving me too hungover in the morning. Seroquel is one of the most sedating of drugs. I now take Remeron and Klonopin for sleep and they work great. By the way, I share much of the same Axis I symptoms as you.
