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

E (022100@1)                            BWell (x2444x@1)it's time for me to sober up

E (022100@1)                            BYes (x2444x@1)it's time for me to sober up

A (x02220@1)                                      EWhen (022100@1)my human frailties have all gotten, the best of me

B (x2444x@1)                                     BWell (x2444x@1)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

A (x02220@1)           EI (022100@1)can be so rough

A (x02220@1)          Ei (022100@1)can be so kind

A (x02220@1)             EI (022100@1)can mend the picket fence

BAnd (x2444x@1)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
