whiskey on the brain 

A near disease like water on the brain. When working a long tedious and tasking day the mere mention of the Jim Beam sends one into a magnetic voyage to the nearest dive bar to drown the working man's woes.

In casual conversation with Andy, Kristine mentioned the bottle of whiskey she procurred for Tom's birthday this weekend. After putting in a crab fisherman's day worth of hard work and sweat, the mere mention of the fine gruel, gave Andy a severe case of whiskey on the brain only to be cured by a stop at the Buzzin Steakhouse on his way home.
