I'm no doctor either, but here's my two cents:
There is no "miracle drug" that works for everyone. It's a hit and miss process. My difficult child was on Lamactil, which didn't work. We tried Abilify, and not only did it not work, but he had some side effects that made it not an option. We tried Depakote alone, then with Zyprexa. Finally, we switched out the Zyprexa for Seroquel, and replaced Concerta with Strattera, and he's been fairly stable for almost six months. He still has some anger management issues, but they are maybe once a week or every ten days, versus several times a day.
You need to find a psychiatrist who will work with you. When we were going through this process for finding medications, he was seeing difficult child every week to assess the effectiveness of the medications, realizing that it would take several weeks for the medications to take full effect. Basically he was looking for subtle differences in behavior to determine if this is the path to go or not. It worked for us.
I hope this helps, and that your difficult child can finally find the right medications for him.
