Addictive Behavior

I have never once felt a need for it,

But never been able to stop for long.

I wish I could hold back, wish I could hold it in,

Wish I could hold my head up against it,

But my head always falls back,

and I always stretch out, yawning again,

and as I drift into unwelcome oblivion

I regret the placement of a comma I won't remember

When I come back to the land of the living.
