Intro

E|--1-------3----------|
Repeat the above a good few times using finger picking
(a thumb comes in handy for the C# note).
Rest of song:
Most of the song just alternates between an C# and a G.
For the two tense "breaks" in the song, fiddle with an Fm like so:
e-3--2
B-1--1
G-0--0
D-2--2
A-0--0
E-x--x
Alternate between the two chords above for these breaks.
And then you get to the "Me myself again" bit where the chords go:
C, C#, C, F, G, F
And then back to C# and G.
Things to try/note:
Try leaving the D# string open during ALL the chords in the song.
