Here's another excerpt from the book I'm working on:
It happened to me sometimes when I went to Center City Philadelphia at night, fixed on the red beacon flashing atop every skyscraper, and definitely when I visited Manhattan. For a while the lights and the sounds and the pace just took me, and before I knew it my mood would be ablaze, my decisions poor, my sleep a short annoyance and my future barely considered. With each pulsing minute my impulse control deteriorated and my ability to make good choices took a thumping. The vibrant city would have been a great laboratory to study what it is that takes me as I turn manic, but I couldn’t handle it and was lucky when someone with me would whisk me away.
