Urgent: I have a singing audition tomorrow and I have a nasty cold, how can I get rid of it on time?

I have a HUGE audition tomorrow. Huge as in, tons of money and awesomeness. I also have an awful cold.

Symptoms: congestion, coughing, stuffy nose, headache, and dizziness. I also sound like a man who has been smoking. Not too sexy.

How can I patch myself up enough to audition? I know I can’t get rid of it completely, but I really need to be able to sing, there is no other time I can audition.

I have a lot of tea, lemon, cough drops, throat spray, sudafed, and advil, but what else can I do?

Please help me. :(
