Jet Lag的詞曲作者是Joss Stone，歌詞也是她本人填的。以下是這首歌的英文歌詞：
Verse 1:
I'm on a plane flying high
Trying to adjust to the time
Got a million thoughts in my head
Trying to figure out what's real
Chorus:
It's jet lag, it's a killer
When you're up and then you're down
It's a whole new day, but it's still night
And I'm feeling like I'm going crazy
Verse 2:
I'm trying to sleep, but my body won't
It's like my body won't listen to me
I close my eyes, but my mind won't stop
Thinking about the life I left behind
Chorus:
It's jet lag, it's a killer
When you're up and then you're down
It's a whole new day, but it's still night
And I'm feeling like I'm going crazy
Bridge:
But I know I'll get through it
I know I'll make it through it
Just gotta keep my focus and stay strong
Through the ups and downs of this thing called jet lag
Chorus: (repeat)
It's jet lag, but I won't give up
I know it's just a matter of time
It's a whole new day, and it feels right
Even though my body says it's night
Outro:
So just keep your focus, stay strong
Through the ups and downs of this thing called jet lag
Just keep your focus, stay strong
Through the ups and downs of this thing called jet lag.
