I'm glad to hear that your sz activity has slowed down, and your epi decreased your med dosage. I haven't been on vimpat, is that a med for primarily generalized seizures? Or is it aimed for partials?
I have been on too high a dosage of a few meds over the years, which can increase sz activity. Have you had any testing to determine how long it takes your body to digest and process medicines? It's an idea that you may want to bring up to your epi ~ see if it's an option. I ought to try this tip myself.
Best wishes to you!
