BCL's 12 Drinks of Motivation

I should drink before work,
It'll keep me from going beserk.
I'll have one to take the edge off.
Well, two just to be sure.
Perhaps three to cure my cough.
And then four to be hardcore.
The fifth drink is for motivation.
The sixth because my boss is a dick.
Seven to sooth my agitation,
And then eight to call in sick.
The ninth I'll have with dinner.
The tenth because wine won't keep.
The eleventh because I'm a sinner.
And finally the twelfth for a good night's sleep.
