Intro: D G F# G
D                 
And when you get tired
Em                            F#  G
Of holding me tight
D                  Em         F#  G
Remember it's how I stay alive
D            Em
When we come down
F#                G
Off our high for the night
             D     Em   F#   G
You don't let go

Same general thing all the way through. Intro also works during chorus.
