"I've been having seizures again."
"Have you been taking your seizure medication?"
"How long have you been off of them?"
"About 2 weeks. Oh, I've been drinking a lot lately and I stayed up all night last night playing video games."
"I don't understand why this started again."
Maybe because you haven't been taking your seizure medications, drank a lot of alcohol and didn't sleep?
Just a guess here.....
