this is so annoying!! everyone in my dept (ok not everyone but 3 out of 8) has been sick last and this week and yesterday I started feeling it too

I took Sudafed 12hr this morning so I can at least breath, but I still can't taste much, I started coughing today and my stomach hurts....
Other then drinking OJ and tea, what am I suppose to do? Oh and my bachelorette party is this weekend - we're suppose to do the Making Strides Against Breast Cancer walk together on Sunday in Paramus, but if it is raining I think I will get more sick!
