Not that I am the next Stanislavski, but did play Hines in PJ Game last year.
For me I always had to remember to be sloppy, and slur. I also used to spin in circles just before going on. Granted, this sort of drunk was played for comedy than anything else.
I hope this helps, and best of luck.
"If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition and then admit that we just don't want to do it." -Stephen Colbert
