The intro is just a walkdown from C to G using
Cadd9, G/B, G/A, D/F#, G

At the end of the phrases in the verse and chorus 
that end in a D, use a walkdown from D to G using
D, Cadd9, G/B, G/A, D/F#, G

Instrumentals follow chord pattern of chorus. Enjoy!

              G
Turn down the lights. Turn up the AC
  G/F#  Em                  D
Hold me close, when it gets cold
         G
Stuck in between, lovin and lonely
G   G/F# Em                    D
Stuck in between, lines on the road

(Chorus)
                       Em      G
It might have been the whiskey, it might have been the wine
                    Cadd9             D
Might have been the moonshine, in her eyes
                   Em      G
It might have been bad luck, it might have been love
                  Am       C/B Cadd9      G
Or maybe just the good time,    it probably was

Wake up scared, 6 in the morning
Reach out to see, if you're still there
These motel rooms, they're always the same scene
I remember a time when I still cared

(chorus)

(Bridge) 
Em                   D
It kicks me when I'm fallin down
Cadd9         G   G/F#
Fallin all apart
Em            D
Try to pick myself back up but I 
Cadd9                D
don't know where to start

turn on the lights. Turn off the AC
pack my bags, it's time to go
stuck in between, leavin and lonely
stuck in between, lines on the road
