Stubborn Mr caff

You are in me
But you react
As though you
Want out.
Is this you telling
Me something?

Caffeine, I feel
You in my blood.
My blood is itchy.
How can that be?
I want you.
I need you
Can you help me?
Stop fighting me.

Red thick lines
Are in my arm.
Stop at once.
Can you do
You work?
My eyes needs
Your help.
My brain needs
Your spark.

Stop your stubbornness
And go do your work.
