Extreme Insomnia

I may go days at a time with no sleep and when i do it is 2 to 3 hours at best.
I am currently taking:
10mgs Valium per day/ 5mgs twice a day
900mgs Trileptal per day/ 300mgs in the morning and 600mgs in the evening
200mgs Lamictal per day/ 100mgs twice a day
100mgs Trazadone per day at bedtime

The Valium has definitely helped my anxiety. The Lamictal has somewhat worked on my bipolar disorder at least my brain is not running wide open 24/7 now. The Trileptal has had a slight effect on my anger issues. The combination has definitely nearly stopped my seizures 100%.
The Trazadone was given to me to help me sleep, but it has so far been in effective and I plan to discuss this in August during my next appointment with my psychiatrist.

I have had insomnia a long time and before I was diagnosed with seizures and bipolar disorder it really wasn't a problem since even without sleep I never lacked energy, but now I do not sleep and stay tired and drained all the time.

I am not the norm when it comes to medication.
Taking Ambian I would drive in my sleep, Serquel and Paxil (not taken at same time) increased my anger 100 fold and my anger without them is really bad to the point I can lift a 200lb man with one hand in mid air when enraged while I have no idea what i am doing while I am doing it. Risperadone and Zoloft (not taken at same time) drops me into severe depression to the point I am suicidal.

Does anyone have any useful information that may help when I have my next appointment?
