Ahhh I am right there with ya'. I Cantor at church tomorrow morning and am currently sniffling away!

My advice though - Vitamin C, and try Cold Eeze lozenges. When you shower make it hot and lightly breathe in the steam through your nose. You can also heat up water in the microwave and do the same, just be careful. Also Nyquil at night and extra sleep should help.

Good luck!
