I think others have covered this topic pretty well. Only personal advice I would add is I wouldn't put a timetable on it. Everyone is different. You might be ready next month or you might be ready in a year.
Just wait until you feel completely confident and comfortable going sober. When you reach the point where your thoughts go from 'I wouldn't mind having a couple drinks at this event' to 'I know I am not going to drink at this DJ party no matter what. It doesn't really internet me.' You'll know you are ready.
I think the key is to always remember how as alcoholics these events are not more fun when we drink alcohol. It's pretty much the opposite. At first when we get a buzz it is but as alcoholics that is not what the end result will be. The rest of the time we will more than likely
-end up getting too trashed
-doing something stupid or that we regret
-losing control of what we say and do
- not remember half of the night
Acknowledging these facts always helps keep me sober when I go out to bars, clubs etc.
