Poem Line - "miles and miles before i sleep"

[AlMac11]

hey, i'm trying to find a poem my brother mentioned to me once. It has the line "miles and miles before i sleep" in it, i think. Also I think he mentioned it may have been an American poem. It'd be great if someone could tell me what it is called. thanks a lot.

Stopping by the Woods on a Snowy Evening, by Robert Frost:

Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow.

My little horse must think it's queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.

He gives his harness bells a shake
To ask if there's some mistake.
The only other sound's the sweep
Of easy wind and downy flake.

The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
