Yes, it's actually really common. Not only for interviewing but for important meeting as well. Besides alcohol, there are other alternatives: - beta blockers as you've mentioned (though you really need to know your normal blood pressure and/or consult with a doctor). - L-Theanine works really well (without any coffee). - nicotine (hit-or-miss since it's an upper for some and downer for others, these are cigars no cigarettes, should not contain any additives but tobacco alone).
