Not a doctor. I'm not really aware of ACE inhibitors as anxiolytics, but beta blockers are pretty classicly used off label for performance anxiety because they blunt the effects of adrenaline (your symptoms are pretty on the nose). Benzodiazepines (like Xanax) are actual tranquillizers, and doctors aren't always thrilled to prescribe them because they can be a bit addictive, but job interview anxiety is a pretty good indication for most docs I think. I'd say most options are better than alcohol, but you're far from the first person to choose that option.
