I always liked the way my father put it:
They say one glass of wine is good for you. Good, have a glass.
Have a second, maybe not as good for you. But the first one was, so they cancel each other out.
Have another, big deal so you had one glass of wine!
Anyway, I agree that how you handle the rest of your life is a better (not perfect) indicator of a possible drinking problem. That being said, there are a lot of functional alcoholics out there too.
I'll say this:
Drinking every day does not mean you are an alcoholic.
Just because you don't drink every day doesn't mean you are not an alcoholic.
Physical dependence is not the only measure of addiction.
Alcoholism is not "just a lack of will power."
I could go on, but people tend to get sick of hearing all I have to say on addiction. I even have a problem with saying "If you constantly ask yourself 'Is my drinking a problem?'" then it most likely is. That may be true for some people, but I know that I ask myself that question all the time. So far, the answer is still no. But it can't hurt to keep yourself in check.
Personally, I drink often but not regularly. What I mean is some days I'll have one with dinner, and no more. Others 3 0r 4. On some Friday or Saturdays, I'll get really drunk.
I am always frustrated by the typical college attitude concerning drinking. As a freshman, I would constantly have people say to me "Your DRINKING? It's MONDAY NIGHT!!!" as I drank a beer while watching a movie. Yet that same person would be out on Saturday getting hammered, puking on themselves and wasting Sunday due to a hangover.
Keep in mind, I often do the same thing (minus the puking). What frustrates me is that most students tend to measure their "responsibility" by what day of the week they choose to drink. Drinking all day every day on Saturday is normal, but splitting a bottle of wine with friends over Wednesday night's dinner is unacceptable.
