I'm on Vimpat and am doing relatively fine now with just one petite seizure every few months (knock on wood), so I've recently been taken off my second drug, Zonegran to shoot for less side effects. I am undecided whether to stay with just the Vimpat or add a second drug, Clobazam. I've read somewhere that Vimpat shouldn't be taken alone, but I hesitate starting another. Is anyone on ONLY Vimpat that can tell me their experience with it as a single drug therapy?
