I'm sorry you and Rhianna had such a tough night. Seizures are very scary.
I am in agreement with both Cathy and Linda in that more testing may want to be considered. My Max has idiopathic epilepsy and it was diagnosed only after all testing was exhausted, which included both an MRI and spinal tap.
Max also has done extremely well on phenobarbital. He takes liver supplements daily which have since proven to help his liver function.
I hope she comes home soon
