10Open the lines of communication.
The person you are concerned about is never going to know you’re concerned unless you voice that.
This may be an uncomfortable conversation for both yourself and the drinker, but it is a necessary one. You could call this an “intervention,” or simply a conversation. Interventions typically are more serious in nature and have more concerned people in attendance, so it really depends on the specifics of the situation.
Whether an intervention or a conversation, the desired end result is the same: bring attention to a loved one’s drinking, and hope they can understand where your concern is coming from.
If they can, they are one step closer to recovery.
