Thrice - Digging My Own Grave tab

I'm pretty sure this is not all correct. This was what I came up with and I'm
hoping another person will see it and correct it and create a more accurate version.

unusual chords (low to high)

Am/F# 4xx210 
Fmaj7 x33210 or to preserve the bass note, 1x3210
Dsus2/F# 2x023x (might actually be 2x0232)

     Am            Am/F#      Fmaj7            E
It's not what you think, just one more little bet,
      Fmaj7         Em                 Fmaj7    E
Just another cigarette, just one more drink.
            Am             Am/F# Fmaj7                     E   
So lend me just a little more, you know cancer can't catch me.
             Fmaj7              Em            F   *    G
Let's have another drink or three. Don't be a bore.

*right after "bore" it goes from the F to the G like this:

    Dm           E               Am             G (?)
But oh, don't I know, I'm just digging my own grave,
    Dm                  E                Am
Can someone else please save myself from me?
    Dm            E              Am      G       Dsus2/F# (?)
And Lord, don't I know, I'm just digging my own grave,
            F                E
Can someone save myself from me?

  Am             Am/F#        Fmaj7          E
I look but don't touch, It's really no big deal.
     Fmaj7          Em               Fmaj7      E
I'll quit it when I feel I've seen enough.
         Am         Am/F#         Fmaj7          E
Oh don't call it an affair, it's just a little fling.
    Fmaj7          Em             F (w/ lead-in from before) G
She doesn't mean a thing to me I swear.

    Dm           E               Am             G (?)
But oh, don't I know, I'm just digging my own grave,
    Dm                  E                Am
Can someone else please save myself from me?
    Dm            E              Am      G       Dsus2/F# (?)
And Lord, don't I know, I'm just digging my own grave,
            F                E
Can someone save myself from me?

I'm pretty sure the ending is just an Am.
