How do I stop my body's never-ending mucus production factory?

About two weeks ago I got a bad case of the flu (presumably H1N1). I feel much better now, but my lungs and nose are still full of ick, (seriously, I could blow my nose for half and hour and not be done, and my chest rattles horribly) and the cough has not totally gone away either. Is there anything I could eat, drink, (or not eat or drink) or medicine I can take that will dry it up?

I have mild asthma and the extra mucus that comes with that is a part of my life, but this is a lot more than normal.

I have taken Mucinex in the past to make it flow freely, but that’s not really a problem at this point.

Aaaand, I smoke. I know it’s not helping me. I know it’s bad for me. I also know I don’t have the willpower to quit anytime soon. Can we just leave that part out of this? Please?
