Seizures?

My 14yr. old daughter seems to have these "seizures" every once and a while. By that I mean, she may black out and be out for a while and not remember blacking out. Or, she just starts to shake and get wierd in the head. The neurologist has put her on 3 different med.'s that make her feel wierd, dizzy, and like vomiting! So, naturally, she doesn't want to take them anymore. He isn't very informative about what her condition is, or how come she even developed this. Since he is the only dr. takes our insurance here, I have to stick with him, unfortunatley! Can anyone help us? I KNOW there must be natural ways to deal with this! Barbara Tweet
