I find that a  
Capo on the 4th fret works best for my voice, but whatever floats your boat. 

C                          Am 
Cheap words falling out of your teeth 
                 F                G 
Rolling off your tongue, like candy 
C                                 Am 
He heard, she heard, you heard me once 
             F                    G Dm 
I won't say it again, now we're just friendly 

       Em        C       Em          C 
With a love gone sour, I lost my appetite 
        Em      C            F 
There's no more flavour, and talking sweet now 
      G 
won't fix it somehow 

Am        F 
Don't Casanova me,  
    G 
I'm over you 
     C    G      Am 
It's over obviously 
Am             F 
Don't put your sugar on me 
G                C       G      Am 
It's too late to sweeten this baby 
        Dm  G(one strum)  C 
hey Casanova, it's over 

C                                    Am 
Cheap words like these will rot your teeth 
                   F          G 
With all the sicky sweet nothings 
C                             Am 
Your speech is good enough to eat 
                     F                G Dm 
But it won't fill me up when I am lonely 

       Em        C       Em          C 
With a love gone sour, I lost my appetite 
        Em      C            F 
There's no more flavour, and talking sweet now 
      G 
won't fix it somehow 

Am        F 
Don't Casanova me,  
    G 
I'm over you 
     C    G      Am 
It's over obviously 
Am             F 
Don't put your sugar on me 
G                C       G      Am 
It's too late to sweeten this baby 
        Dm  G(one strum) 
hey Casanova, it's over 

Am        F 
Don't Casanova me,  
    G 
I'm over you 
     C    G      Am 
It's over obviously 
Am             F 
Don't put your sugar on me 
G                C       G      Am 
It's too late to sweeten this baby 

    F 
Casanova me,  
    G 
I'm over you 
     C    G      Am 
It's over obviously 
Am             F 
Don't put your sugar on me 
G                C       G      Am 
It's too late to sweeten this baby 
        Dm  G(one strum) C(If you want) 
hey Casanova, it's over
