By afternoon, I felt kind of like there was something in my lungs and I needed to cough, but couldn't.
By the evening, I was starting to feel really run down, I was coughing (but not bringing anything up), but my temperature was only 98.7F.
This morning, my throat is sore, I'm coughing up nasty stuff, and my temperature is up to 100.4F, and I feel very tired. Damn that was fast.
