Can Alcohol Make Some People Mean, Even If They Don't

Can alcohol make some people mean, even if they don't get drunk? My husband when having one, two or three beers could be fine but can get very to someone at the drop of a hat. This volatility can last into the next day. He can like a, 'Jeckle and Hide', situation. He can get crazy angry and say the most hurtful things, to purposely hurt. Other wise he is a kind loving man. In fact he never admits to what he's done or said; and will not say he is sorry. Though if anyone even points out something he has done that is unkind, he reacts hurt, angry and insulted.You are suddenly the one in the wrong, being labeled a trouble maker. Now he has a reason to be indignant and angry. Thank God he doesn't drink all the time. We've been married almost 36 years!! I've noticed this sensitivety to alcohol since the beginning of our marriage. Is there a sensitivety to alcohol?
