I've discovered that megadoses of Vitamin C have worked for me. It was too late to go the doctor, and I only had Vitamin C (as Sodium Ascorbate powder) on hand, so I chugged that down, up to maybe 5 grams every half-hour in orange juice, and about 6 hours later, the worst of the flu was gone. Next morning, I was feeling like I only had a minor cold. The flu never came back, either. Since then, that's been my go-to strategy.
