There was a bad seizure a little after ten p.m. I came to on the kitchen floor. And often after seizures, if there is not deep, deep sleep, here is insomnia. Like now. I've been dozing for hours, and just took a second Ambien. I'm sitting here at my desk, while the neighborhood sleeps. While the house sleeps. My mind is racing. Such profound quiet. Only the faint hum of the fridge, a fainter clicking from the baseboard radiators.
