Yes, it is generally possible to leave an Alcoholics Anonymous (AA) meeting early. AA meetings are meant to be voluntary and respectful of individual members' needs and preferences. While it is encouraged to stay for the entire duration of the meeting to get the most out of the experience and show support for fellow members, nobody is obligated to stay for the entire session.
The principle of anonymity in AA means that members' attendance or participation in meetings is kept confidential. So, if you need to leave early for any reason, you can do so discreetly without drawing attention to yourself.
If you find that you frequently need to leave meetings early, it might be helpful to discuss it with your sponsor or another trusted member. They can provide support and help address any concerns you may have. Remember, the primary goal of AA is to provide a safe and supportive environment for individuals in recovery, and that includes understanding and accommodating individual needs.
