Overdose

Intro:
The intro is the  B  and E  chords. Tabbed out, it looks like this
-0------0----------------------------
-2------2----------------------------
--1------2---------------------------
---2------1--------------------------
----0------0-------------------------
----2------0-------------------------
No, that's not а mistake, you have to strum it like that
for the intro. Not sure how many times it is, you'll have
to listen to the song to figure that out.

Verse:
The Verse riff is simply   A - A - C - D - C   
Of course you have to listen to the song to figure out 
precisely how to strum these chords.

Chorus:
This is the part where he says, I overdose on you then you
just have to hit the chords  A - C  after everytime he says I
overdose on you...

Outro:
The outro is the same as the intro, but the speed changes
in the outro, and you have to listen to the song to figure
out precisely.
