here is the way i figured out the song.
I slightly altered the main riff to better fit what my drummer is doing..but just the last 4 notes...

MAIN RIFF
G .......
D ........454
A ...........42
E 2..22........540

Chorus.
"I'm not the one....enter my veins"               
G ................ | ................
D ........42...... | ................
A ...2.24...4..242 | ...2.24.........
E 2...2......22... | 2...2..2.5554540

 " and i dont remember why i came"
G ............... |
D ............... |
A ...2.24........ |
E 2...2..2...0.22 |

try to imagine each . as an 1/8 note.. this might help get phrasing better..
