I recommend that people procure a supply of NAC (N-acetylcysteine) for lung prophylaxis and start taking it. A fair amount of peer-reviewed research available, including its influence on the cytokine system. As those of us who weathered the bird/swine flu and SARS scares learned, it is often the cytokine storm that kills you. One unanswered question: what dose? The response may be curvilinear.
