We didn't know

My four year old was diaganosed Friday with seizures after she stopped breathing on me and I did CPR on her on the side of the hughway. Followed by her doing it twice more in the ER where they had ro assist her wirh breathing. I know know this is common. What isn't common I hear is the way most of her seizures present or at least the way they were prior to Friday. For the pasr 5 month she had "episode" where she would immediately stop doing whatever it was tell us she was going to throw up and then end up spitting up about a tablespoon of saliva followed immediatlybwirh saying her head hurt and then immediatly wanting to be held and falling asleep wirhin minutes only to sleep for 20 min or 2 hours. All the Drs were saying she had migrains. Even in the ER where a nurse, ER Dr and a nerologist seen her do an episode that time withe stopping of breathing they all said it doesn't appear to be a seizure. Her eyes never stare off, she never jerks and she always remembered at least until Friday when she had the big ones. Then Friday night she had one like she had been having at home and we captuted it on the eeg and was told it was defiantly a seizute! Over the last 5 months she has had no less than 75 of these and we never knew! We just thought they were headaches! Have you ever heard of a seizure being like this? We are now on Keppra day 4 of it and she is a differnt person. I am heartbroken she is very quiet doesn't want to talk or play only sut as if she is in a daze. Will it get better? Does it take time to adjust to Keppra? Please help me!
