I wouldn't like to say whether you are and alcoholic or a hard drinker. Hard drinkers can stop or moderate if they have a good enough reason. They drink a bit like you do, excessive but regular amounts, never losing control, never suffering the insanity that goes with chronic alcoholism. Drinking is just routine, doesn't disrupt work or family life. I used to envy people who could drink like this.
However, hard drinkers can still suffer withdrawals, and they certainly suffer all the adverse health effects that the real alcoholic suffers. Like all kinds of cancer, heart disease, organ failure diabetes and so on. Even if you are not alcoholic, drinking as much as you do just about guarantees an early and painful death. Hard drinkers can stop or moderate of they choose. What will your choice be?
