I am new here, but have some experience with seizures...I had many grand mal seizures as a young adult, directly related to some illegal drug abuse. That was many years ago, but remember em like it was yesterday.
After reading your post, i don't think i saw any mention of any seizure meds..
IMO if you've experienced more than one seizure in a short amount of time, you should be on some type of anti seizure med...
No matter what the cause, seizures are no joke, and meds can help one remain seizure free until all underlying causes are treated.
Good luck to you...i feel for yeah, as seizures are NO FUN...
