The thing that a lot of people do not know is who needs to initiate an alcohol intervention, and the appropriate time to hold one. One thing to be aware of is that any time you're able to hold an alcohol-related event is likely to be a fun moment because the main issue that people face is the inability to bring everyone in their family and friends all together at the same time.
Strategies for preparing an alcohol intervention
The primary suggestion is to form a good-sized group and discuss the events taking place and how the participants feel. If you're only having only a handful of people, it will not show that you care and love them and, as a result, they won't be as enthused about the process as they ought to be.

Make a party
One thing that really works is to make the event be a celebration instead of an alcohol-related intervention.
Do not provide alcohol
The worst option you have at an alcohol-related event is to provide alcohol to other people. Inducing the person you're trying to help is not an ideal way to begin on the path to an alcohol-free life. This could be a good test in the future however for now, they need to be aware of the consequences they're causing to family and friends before confronting their own issues.
Taking Care Of The Person
The most important thing you should be aware of is that you shouldn't ever attack the person who is the cause of the issue.
