Here's the opening riff:2D 3D-b 4-5D warble 4D-b 4B 3D-b 2D 2D-bb 1D
2D 3D 4D-b 4D 4D-b 4D (sus) 4D 4D-b 4B 3D 2D(sus)
2D 2D 3D-b 4B 3D-b b4D b4D 4D-b b4D b4D 4D
b4D b4D 4D-b 3D b4D b4D 4D 4D-b 3D 2D(sus) 2D-bb 1D
I've introduced new notation for what's know as a "dip bend" = b4D this could be written as 4D-b 4D but that could imply two notes. This notation means that the articulation and attack on the note is such that it starts in the bent position and quickly releases to the natural note.
Hopefully I can make some progress on the rest of the song, let me know how you're doing with it.
Good luck
Alan
