My pleasure @dolphfan!
Thank you for sharing that information about your sister. An epilepsy diagnosis typically requires two or more unprovoked seizures, so it's wonderful that she hasn't experienced any since.
After my diagnosis, I discovered that certain mood stabilizers can actually increase seizure activity. A psychiatrist prescribed me a mood stabilizer about a year before I was diagnosed with epilepsy, and it made my seizures worse.
Have you reported to this doctor who prescribed this mood stabilizer to you?
