Alcoholic behavior is something that goes on over time, and gets worse as it goes. When the drinking behavior associated with alcohol starts to ruin relationships, and may interfere with work and other activities, there is a problem. That can not be your guide completely though, as some alcoholics can live and lead normal lives without it interfering with work and family. They are still suffering, hurting their bodies, and will eventually hurt their families, but some function rather well for a time. The first problem with alcoholic behavior tends to be alcohol abuse. This does not mean that someone is yet an alcoholic, but it does mean that they will be if they do not stop what they are doing.
