I agree that drinking too much can be like eating too much.
Alcoholism is a disease, but I don't know if that was the 'only reason' I drunk a bottle of nice wine most nights. There are degrees of alcoholism. I lived with a chronic one years ago and that was frightening to witness.
Like any addiction I think it was trying to escape from myself, 'change my state'
We need to address what the discomfort is we are trying to escape and once we face it head on you might find out that's a lot easier to do than trying to avoid it
