Last night I went to bed with a pounding headache. Needless to say, I didn't get a full night's rest & to make matters worse, when I did arise from the little sleep that I did get, the pounding headache had evolved into a raging headache. All I could do was pop some Advil, inform my supervisor that I wouldn't be in today & go back to sleep. By the way, it was the 1st time I've called in sick in like 2 years. The rage within has now subsided & I am now feeling better.
