You can buy Tamiflu from International Antiaging Systems without a prescription (ships from Europe).
Oddly, you should have some Tagamet (cimetidine is the generic). It can disrupt the cytokine storm that destroys your lungs. Don’t take it until you experience EXTREME respiratory distress.
Life Extension Foundation, Vitamin Research Products, and Durk Pearson’s website all have good articles on surviving the flu.
The current H1N1 is showing a high level of resistance to Tamiflu.
