Hi there and welcome to Neurotalk! I'm so sorry for all that you and your hubby have gone through - sounds like he really needs to be evaluated by a Neuro and get the correct meds to control his condition.
Here's the link to the Epilepsy and Seizure Disorder forum. Hopefully someone there can give you some recommendations or suggestions.
