I am nothing without coffee

I drink coffee 
like some people snort coke.
I drink coffee
like some people shoot heroin.
I drink coffee 
like some people gamble.
I drink coffee
like some people go to AA meetings.
I drink coffee
like some people horde money.
When I am out of coffee
you can find me trembling
in the corner; stevia and half
and half, alone, just don't cut it.
