My best friend's brother has seizures...sometimes from low blood sugar (he is diabetic), other times they don't have a real cause for (the doc's have just said he has a mild seizure disorder)

Anway, I have not been there when he has had one, but my firend said he gets very mean when he first wakes up... he generaly has them at night, and doens't know why everyone has woken him up in the middle of the night, doesn't believe he has had one, wants everyone to leave him alone. The next day he usually has a bad headache and is tired.
