That was how it got me.
I think maybe the constant traveling and working plus the heat combination finally downed my immune system. I looked like a sick dog.
Through out the night I kept coughing up gooey globs of mucus. At one point, I though I might cough up my lungs from the way the mucus was sticking hard to my lungs cells. When morning finally arrived, I lost my voice but my chest felt lighter (mucus expelled by the medicine I took).
Went to work today but I think the cough is getting better.. although I try not to talk too much. No rest for the sick.. too much work to do!
