I unsuccessfully tried under doctor supervision to come off of Dilantin after five years of being seizure free. They think a head injury I sustained 10 years ago is the root cause of the issue.

The doctor put me back on the medication and things have been relatively good since, 3 weeks. I recently have had two instances where I was under pressure and experience high anxiety that I have never felt before but I did not have a seizure. I have experienced a dulling headache after both of these occurrences. I am taking 4 X 100mg once a day and was wondering if the medicine was no longer working for me. I realize it's only a guess but do you have any thoughts?
