I personally don't think adderall, or Dextroamphetamine goes well with booze (or mixed with any depressant). Alchohol will likely negate the effects of the amphetamines, which might prompt you to take more, starting a dangerous cycle.
What I do with Adderall and Benzo's (I don't drink, but benzodiazepine's and alchohol are similar in action), is take the adderall first, and save the benzo (or another CNS depressant like alchohol, opiates etc) for the come down. I also have found that taking the depressant 30 minutes to an hour before the stimulant, is a decent experience as well. But when you mix them together, the depressant will most likely over power the amphetamine, or dull it's effects. This isn't always the case of course, I used to mix stims and depressants all the time, heroin and cocaine was my favorite combination. But Adderall is longer acting and IMO doesn't give as much of a "push" as cocaine, methamphetamine, MDPV etc..it's a more subtle experience.
