Suggest Remedy For Seizure Symptoms While On Trileptal

my daughter has been on Trileptal for seizures since she was 15 yrs old. She is now 23, almost 24. Since on Trileptal, the only "episodes" she's had has been when she skipped meds. She made it through a complete pregnancy and had a healthy baby boy, September 2012. She went on mirena for birth control after. Since then, she has had some "suspicious" episodes. ONce, right after mirena was inserted. She felt "wet", but wasn't sure if she had seized. Then she had another episode where she wet herself in her sleep. (She's never wet herself during seizures that have been witnessed.). Last week, she fainted at work and they are not clear if it was a bad fainting or an actual seizure. Hand switched. They caught her so she didn't hit her head. Her Magnesium and Potassium were low. She's really scared that either seizures are getting worse or meds not working or just not sure.
