The whole song is three chords, E A and B
Here it goes...

E5                              B5
Well it's time for me to sober up

E5                              B5
Yes it's time for me to sober up

A5                                        E5
When my human frailties have all gotten, the best of me

B5                                       B5
Well then I know that it's time to sober up

Yes it's time for me to sober up
No more time to say "Bottoms up"
When everyone I see is looking, funny back at me
Then I know that it's time to sober up

A5             E5
I can be so rough

A5            E5
i can be so kind

A5               E5
I can mend the picket fence

B5
And I can have an open mind

Well it?s time for me to sober up
Like the old saying goes ?I guess enough is enough?
When my academic proclivity is not exactly, what I hoped it would be
Then I know that it?s time to sober up
