Chocolate, stress and colds

I'm getting a cold. Or, to be more precise, I've been getting a cold for more than a week now. I'm fighting it in the old-fashioned way of the Svanevikian clan; by ignoring it and going to work of course. And it's been working out pretty good. I'm dead tired, my throat is sore and I have headaches and dizzy spells all the time, but I'm not completely dead yet. But I'm not completely recovered either, and now, there's only a few days left before the larp I've been looking forward to for ages and I really don't wanna be sick while I'm there.

So what should I do?

I'm a strong believer in the helpfulness of working in stressful working environments so I'm going to continue doing that, but I need more good tips. Right now, the only thing my body seems to be telling me is that I would get massively better if I eat an enormous amount of chocolate and wasabi peas. I kid you not, I have an intense craving for dark chocolate and wasabi coated green peas. Preferably together. And I cannot shake it. Should I listen to my body? Is it telling me the truth, or is this some sort of sick joke where I eat everything it tells me to and I still get sick? It seems like something my body would do... Do you guys have other good tips on how to shake a cold that does not include resting ('cause I really don't have time for that guys)?

*fingers crossed*
