Alcoholism Support Group
Alcoholism is the continued consumption of alcoholic beverages, even when it is negatively affecting your health, work, relationships and life. If you think alcohol is causing you to lose control, it's time to seek help. Our group is a safe place to vent, check in, get back up if you fall, and reach sobriety.

It's a lighthearted joke in AA. Sobriety needs to be fun otherwise we wouldn't stay sober. It means that journey's not over, it's one day at a time and to keep working your program.
