[Verse 1:]

I know, what I've found
What I've found, I know
It's nice, it feels cool
It's how it should, simple

[Chorus:]

Lately I've felt so great
You're the best drug I take
My head has gone crazy
What have you done to me

Now I know, I know, I learn to breath [x 4]
I learn to breath

[Verse 2:]

I know, what I've got
What I've got, won't let go - ha!
And my thoughts, in my head
I'm stupid and simple

[Chorus]

Now I know, I know, I learn to breath [x 4]
I learn to breath
Well I learn to [x 3]
My girlfriend
