Lyrics:

You're the reason I don't sleep at night
I just lay here at night, toss and I turn
Lovin' you so, how my heart yearns
You're the reason I don't sleep at night
Walkin' the floor, feelin' so blue
Smoke cigarettes and drink coffee too
You're the reason I don't sleep at night
I'm bettin' you're not losin' sleep over me
But if I'm wrong, don't fail to call
Come over and keep me company
Sometimes I go for walk, take a look at the moon
Strum my guitar and sing out a tune
Honey, you're the reason I don't sleep at night
