I listened to it many times and it didn't sound completely correct with open power 
chords, so I Capo the 2nd fret and it sounded MUCH more like the original. Enjoy :).

[CAPO 2]

Intro: G   Em   Am   D

G                                    Em
Take away the sensation inside
Am                                     D
Bitter sweet migraine in my head
G                                                   Em
Its like a throbbing tooth ache of the mind
Am                                      D
I can't take this feeling anymore

[Chorus:]

C                                                  G
Drain the pressure from the swelling,
C                                                   G
This sensations overwhelming,
C
Give me a long kiss goodnight
        Em
and everything will be alright
Am
Tell me that I won't feel a thing
D
So give me Novacaine

(Play Intro again)

Out of body and out of mind
Kiss the demons out of my dreams
I get the funny feeling, that's alright
Jimmy says it's better than air,
I'll tell you why

[Chorus]

(Play G until solo)

Oh Novacaine

Chords during solo:
Em   G   C   G   Em   G   Am   D

[Chorus:]
Drain the pressure from the swelling,
This sensations overwhelming,
Give me a long kiss goodnight
and everything will be alright
Tell me Jimmy I won't feel a thing
So give me Novacaine 

(Play Intro again, end on G)
