Vrylar is an antipsychotic and a mood stabilizer. I assume you mean you also want an anticonvulsant like Lamictal?

Lamictal is nice due to the fact most people don't have any side effects. Another option is lithium, but you have to watch your kidneys with that one.

I do think it's weird you're not on an anticonvulsant in addition to the AP. Definitely ask about Lamictal due to its lack of side effects.
