It was the same with my father. He was a alcoholic, but his real problem was he knocked up at girl at 19, married her, then by age of 21, had a stay at home wife, 2 babies, a boring job during the day and went to school at night. And hated it. He'd had other plans for himself. He didn't love his wife. He resented me (the oldest baby). Work was a drag. And he had always wanted something else--but got himself trapped and didn't have the guts to untrap himself honorably.
So he drank. And made himself and everyone around him miserable. Until he killed himself driving drunk.
His drinking was just a symptom of his weakness of character, his cowardice, and his bitterness and blaming everyone else for his situation rather than himself. The Jack Daniels wasn't really the problem.
