Is drinking alcohol alone bad?

Let me give you a situation and you tell me if this is bad

So I guy who is relatively happy. Has friends and family. Has a job and is cared about.

He drinks alone 3 times a week. Sometimes it’s 1 beer Sometimes 4 sometimes a half bottle of whisky etc

He feels happy doing this and loves watching TV and listening to music when he does this.

Is this bad/wrong?
