I'm drinking usually 1/2 to 3/4 bottle of wine with my wife ( 3 glasses ~ 3/4 of 750ml ) and it's like shocking to see how people around us react on that fact.
In Germany, people are very secretive on their alcohol consumption, although I've seen germans having 5 beers on Friday, instead of having a beer per day - they usually don't share those stories. This makes me feel like I'm having an alcohol problem as well ... but.
On the contrary, when I was in Portugal, people usually had a glass of wine for lunch every day.
Keep in mind that Moderate consumption [1], according to wikipedia is 300ml per day for men ( bottle is 750 ).
I think your problem is more of a "am I loosing control" kind of a problem, so you can just stop drinking for a while ( usually I don't drink any alcohol or coffee in January - cleaning my body ) and replace the glass on your computer with a cup of tea.
