5:00 Wall

The hardest part of my day is between 4:00 and 5:00 p.m.

I'm not sure if it's a blood-sugar thing, but I just totally run out of gas in that last hour before my wife comes home from work. By 5:00, I absolutely hit a wall and can hardly hold my head up.

Maybe it's because my day begins at 7:30 and goes straight through until that 5:00 mark.

Maybe it's just a natural lull in those biorhythms people used to talk about years ago.

Maybe it's all psychological.

Either way, I'm pretty sure I'm not the only one who struggles at the end of my shift. How do you overcome your "5:00 Wall?"
