My mind feels like a race car on the track, getting faster and faster every time I pause to think or blink or try to focus on anything. Nothing can keep up to it, not the other cars, not my body, not anyone else in the bar. It’s a rush, pure exhilaration, and I’m having the time of my life. But instead of driving, I’m in the passenger seat, along for the ride, watching myself race around the track from my barstool.
