Why It's Called POST

During the war I could sleep anywhere

Today, a full nights rest is rare

Fifty years ago I slept leaned up on a tree
I slept through rain, mosquitoes and artillery

I slept through the hot scorching sun
I think I even slept while on the run

I have slept at noon
And I have slept through a typhoon

But today is a different story
I have nightmares that are gory

I have insomnia with a roof over my head
Tucked into my own warm bed

I have a woman next to me who is a dear
But I still can't sleep for all of this fear

This must be why it's called POST Disorder
My reality sure is out of order
