It's one of those days when you wake up in the morning feeling light-headed, aching back, stuffy nose, neck cramps, and other ill feelings that makes you not want to get up.
Can it be "Monday sickness" for the working people?
Can it be "I'm too stressed at work" for people needing a time to relax?
Can it be "I'm just ..." for no apparent reason at all?
What's it for you?
