Wrong time to be sick, seriously..

Exams are 12 days away.. and i hate falling sick when i need to pay a visit to Monash Medical Centre for my surgical selective, plus study 13 weeks of semester 1 stuff as well (why in the world do they have to include it in this mid sem exam..). Runny nose and coughing for more than a week already, yet i'm stingy to the point of not wanting to let the university's doctor rip me off.. Currently self-medicating with tonnes of cold and flu meds plus Robitussins' (wait, isn't that what unethical doctors do..?)
