Styx,
I can't offer advice being a run of the mill recovered drunk with the time to post being re-tarred and all. I can strongly recommend you keep your docs counsel. If he is one of those that always whips out the scrip pad, well, substitution doesn't help at all. I don't have any tips, but I am rooting for you from the bleachers. Give em one for the Gipper! We got your six.
(oh and try yelling in the mirror "Boy! AM I . . . you know the rest! Can't hurt unless the neighbors hear)
