Drinking problem: someone who turns to alcohol to cope. Those I know typically don’t stop at a third or half a cup but can polish off half a bottle or more at a sitting. This is not a scientific definition but one based upon personal observation and opinion. I don’t know many with this problem, but, then again, I don’t know many who whip out the wine mid-week for anything.
If one can sip a little for flavor, ok, maybe.
Alcoholism is an addiction. Think of smoking. If someone does it recreationally, they’re teaching their bodies to get used to the nicotine and may have to fight wanting more. So too with drinking. It’s a pandora’s box. Why open it??
