@tarnie23,
Remember that this classification of anti convulsant/bipolar divalproex like serotonin reuptake inhibitors can treat the manic phase however no one knows how they works or why they work.
That is why individually treatment are the best course because of their unpredictably. This is really a question for your pharmacist. I just wanted to point out that not only are we in the dark about how and why we don't know why they help some and make the other worse and some people they do absolutely nothing.
It is the law in America that every time you pick up a prescription the prescribe must ask you 'Do you have any questions about this medication'
That is who you need to talk to.
