best remedies for chest congestion?

[kangamitroo]

i run into this every winter and have obviously not yet found what works for me.

1) i need to relieve the pain in my ears and congestion in my chest.  other than a steamy shower....?

2) i'd like prevention suggestions, so i can avoid this.

garlic tea at the first sign of cold, to ward it off?  any other ideas?

thanks so much!
