IMO it's a bit uncharitable to presume a person did not think through his new position. Generally novel events cause people to think through their life's choices. Dropping off alchohol has zero downside and will statistically improve health a bit if the drinking has been only moderate. If one yearns the social meetings one can drink non-alcohol drinks and still have a good time (unless the person has severe anxiety issues and is using alcohol as cure).
