Just wanted to add that drinking only on the week end does not mean you don't have a serious problem and won't suffer the consequences.
One of the old timers in my home group was a week end warrior, had a good job, good family man never in trouble with the law except on the week ends he would go hang out with his friends get drunk and race his car!!!
He was in a very bad crash once but kept his pattern, work and be sober all week and drunk race on the week end until a judge and AA finally put an end to that.
Our alcoholism come in different shape and form but it is still alcoholism.
