I saw someone reccomending both Zicam and Airborne, but both of these are remedies for the preflu or beginning flu stages, and would not provide as much help now that you have had it for a while.

Zicam essentially claims to prevent symptoms from starting, which I have used it for and it was effective, but also claims to shorten symptom times, that I am not sure of. Airborne is essentially vitamin C times a million. So it builds up your immune system before colds, but it could help with a flu I guess.

Just be very careful if you do decide to take Airborne because too much of a bad thing is possible and you can have too much vitamin C. So don't overdo it, your body can only retain a certain amount of vitamin anyways.

Good luck and feel better.
