I don't really know if there is a difference. I do however think it is something for each person to decide. Sure people can look at the behavior and some and say "yikes, you drink too much" But there are also other times people will minimize the problem. I have had many people say to me "come one, it's not that bad. Just drink a little bit less" But I think that even if I am drinking one glass of wine, once a month, but it is something *I* feel uncomfortable with and something that *I* think is a problem then it is, it is not for anyone else to tell me it is not an issue, not even a doctor.
