                        \__________/ 
 
The first little riff is:

e|-----0--------------|
B|-----3------------0-|
G|-----4--2---2-2-2---|
D|-2-2--------0-------|
A|--------0-2---------|
E|-0-0----------------|  x3


Then the verse is:

|-------------0----------------0------------------------------------------
|--7/\--5---3-------7/\--5---3----------3-0-----3-0-----0-----3-0-----3-0-
|---------------4----------------4------------------0h2-------------------
|-----------------------------------1s2-----1s2-----------1s2-----1s2-----
|-------------------------------------------------------------------------
|-------------------------------------------------------------------------

also times 2.

The pre chorus (I hope you've changed the...) is then

|-------------------------------------------------------|
|-------0--------0---------------------------0--------0-|
|-----5--------7----------7--------7-------5--------7---|
|---5--------7----------5--------5-------5--------7-----|
|-3--------5----------7--------7-------3--------5-------|
|-------------------0--------0--------------------------|

And the chorus is..

|-0--0--0--0---0--0--0---|
|-0--0--0--0---0--0--0---|
|-2--5--7--7---2--5--7---|
|-2--5--5--5---2--5--5---|
|-0--3--7--7---0--3--7---|
|-------0--0---------0---|

There's the "You're so full of venom that you'll spit into your own 
sweetheart's face....ah" bit, as well, which goes:

|--------------------------------------6-------5--------
|-------0-------0-------0-------0--0-------------4------
|-----0-------0-------0-------0----0---3----------------
|---9-------9-------7-------7------5--------------------
|-7-------6-------5-------4--------3--------------------
|-------------------------------------------------------

Then anything else is just variations on the above bits.
