When David was drinking

[Bassim]

I am wondering if my sentence sounds natural.

When David was drinking, he could spew out all kinds of insults and abuses, which was the main reason his friends did not like to go out with him.

Is David no longer drinking? He's given up the habit, I mean.

In case any other learners are wondering why ingesting a liquid would make someone abusive, note that the opening phrase "When he was drinking" (in this context) includes the implied fact that it refers to alcohol.
