The only thing that will make me feel like I would be good to be able to sleep as well

 Numbing the pain

Drugs, alcohol and mostly cocaine. 

Dealers know me by name. 

Big dog you're the best customer 

Your craic is mighty. 

But truth is inside I'm dying. 

The cocaine use to be for hiding. 

But the mask falls, 

One line and a tear falls. 

Staring at empty rooms and pictureless walls

Hunting my own house. 

Hunted by old ghosts. 

The toss and turn as the drink wears off. 

The bed is not comfortable. 

Blood stains and tear drops on the pillow. 

The doctor can't prescribe an antidote. 

I'm lost, but not quite given up. 

But how long can cocaine keep you up?
