Sick during Csection?

Liz • Baby #2 due 12/24!
I have a scheduled csection for 12/17 and I'm really sick! Sore throat, mucus, stuffy nose, clogged ear, and a cough that makes me vomit! I've been trying to get lots of sleep, drink water with lemon & honey, and I'm taking over the counter meds but nothing has seemed to help. Any ideas?
