I used to look at that question on "are you an alcoholic?" surveys, "Do you drink alone?" and laugh. Who were they kidding? Don't most people drink alone?
I've had two years sober and now the question makes sense to me. It shows you are drinking for the effect, to numb yourself, check out.
I also used to laugh at the two drinks a day limit set by health experts. Who were they kidding? Again, now that I have some distance between myself and alcohol this also makes sense. Most people I know rarely drink more than two. In fact, most people I know barely drink at all.
I've read that normal people start to feel uncomfortable or "full" of alcohol after two drinks. They don't feel the need for more.
