A few days after lowering my dose, I was walking in Hyde Park, along the side of the Serpentine, when I realized that my steps were literally bouncier than they had been and that I was taking in sights and sounds that previously had been filtered through thick layers of gauze. The quacking of the ducks was more insistent, clearer, and more intense; the bumps on the sidewalk were far more noticeable; I felt more energetic and alive. Most significant, I could once again read without effort. It was, in short, remarkable.
