influenza
"My son and wife both came down with bad cases of the flu, and I started to experience extreme chest tightness, cough, and fever about five days later. Took my first dose of Tamiflu about 15 hours after experiencing symptoms, and within 12 hours was feeling 50% better. Within 24 hours was 90% better. No side effects. Simply a miracle drug, and everyone should have a box in their medicine cabinet."
