Do you want to stop drinking?
Do you think you need to stop drinking?
I think when we get to the point where we start to evaluate our drinking it has already become a problem. Or as the common response I have seen goes, "If you think you have an alcohol problem, then you don't have to ask."
Try abstaining for a few months. If you have a difficult time doing that - or can't - then it's what you should be doing.
