Ugh, hate Sundays… by the time the clock’s hands tick round to about 5 o’clock in the evening, Sunday blues set in. Sunday blues should be a recognised condition. It is characterised by a nagging feeling of impending doom, general sluggishness and a paranoia about running out of time. These feelings persist for a good few hours before bed time and may even keep you from sleep. This may trigger the secondary condition.. Sunday night sleeplessness. As you lie there thinking of (a) things you need to do tomorrow and (b) things you SHOULD have done on Sunday in preparation, sleep eludes you. The longer you lie there the more you worry about the fact that you can’t sleep. It’s a vicious cycle made all the worse by the fact that it is Monday in the morning. Tossing and turning exacerbates the situation and should not be entered into lightly. Consider yourself warned.
