Zicam or Cold-eeze or any other zinc supplement, though at this point it'll probably do you no good on this round
Here's my timeline: On Monday, my buddy Albert has the death cold and drove my car. Then I saw you Wednesday and you coughs and snotted all over me and my car. On Friday, I started to get eh familiar tickle and immediately started dosing myself with zinc. I worked on Saturday and then (admittedly) basically stayed in bed all day on Sunday and Monday. Yesterday (Tuesday), I had a bout of sneezing and coughing, but as today progressed, I feel like I'm beating it.
So zinc poisoning.
