Hi Cedar,
I ask myself if your on to many AED's that are interacting with each other. I found the best AED for cateminal sz. is diamox because it gets rid of the extra fluids in your body that can cause sz. I would take the pill for only 5 days each month a week before my period and it made a big difference in the amount of sz. I had so then my neuro put me on it full time.
You might want to ask your neuro to do the e.e.g. right at the hospital so they can watch you to play it safe. I feel that the e.e.g.'s they do at the hospital are much more acurate than the ones at home but that's just my opinion. Here's wishing you well and May God Bless You!
