Toddler with Benign Rolandic Epilepsy

My daughter will be turning 3 this week. She was diagnosed with Benign Rolandic Epilepsy. The neurologist was very confident about the diagnosis based upon my wife's description of the seizures. Daughter had an EEG (no idea if it showed anything; we were tired and may have misunderstood what he said about that). MRI was negative for problems. A little history - For the past 6 months or so, my wife has seen weekly occurrences of what she assumed was my daughter making strange faces (this involved cheek twitching and lip quivering). We did not realize it could be a serious problem until she had an obvious seizure (simple partial) last week. The ER sent us home after the ER doctor happened to witness and identify one of the minor twitching / quivering seizures. Several other cheek twitching / lip quivering episodes followed, culminating in another obvious seizure, this one involving hyper salivation and slurred words. What is troubling about my daughter's condition is that we have seen many daytime seizures, and that recently the seizures seem to cluster together. No idea if there are seizures occurring at night. We were given a prescription for Kapra, but are still weighing the risk / rewards of giving the medication to a toddler. Any comments on that? Another question. After returning from the hospital, daughter experienced a round a vomiting lasting from 3 AM to 11 AM, followed by additional vomiting the following morning at around 2 AM. Nothing sense then. She has not had an appetite, is drinking fine, and otherwise appears healthy. The hospital says it can't be a reaction to the medicine she was given. If not for the recent diagnosis, I would assume she picked up a virus at the hospital. Is it possible her vomiting is the result of a seizure? I should add she had a vomiting spell last month (1/night for 2 nights).
