I've been on dilantin for over ten years and while I was not seizure free I was concious during my seizures and still able to drive. The traumatic birth of my second child (sept. 2008)--I nearly died--and the hormonal changes have changed my seizures. Now, I cannot drive. I tried clobazam with dilantin. It hasn't worked. Today my dr. said to try keppra with my dilantin. I looked at some past postings on this website and most of them are about horrible experiences with Keppra and mood swings. Is there anyone out there who has taken it and found that it worked well without the side effects? I'd also love to hear from anyone who is taking it with dilantin.
