Out of Sight Addiction

Don't do it
Why would you?
You want to
But you wont
I keep you from it
From it's addiction

But...
I am your addiction
Some are good
Some are bad
Which am I?

I help you
As you help me
If you get addicted
to something else
You start to lose me
As I lose you

You drift away
I float
And further we get
We're lost
and out of sight
We're gone
and out of sight
