Depending on the size of your pour, that's close to an entire bottle of wine every night.
You're an alcoholic. It's hard to face that failing in yourself, but if you consider it an illness rather than a personal weakness, you can treat it and win. If you don't, it will probably cause your premature death and make certain aspects of your life much worse than they might otherwise have been. People who drink that much, for example, make poor life decisions. Maybe you sleep with someone you shouldn't, or forget birth control, or accept a ride home from someone who's dangerous, or with someone who's been drinking, too. Those kinds of mistakes can bite you, bad.
The sooner you face that you're an alcoholic and stop completely, the better for your health. While you're young like this, your body is better able to repair damage, but if you continue, it cannot. Liver damage is common and can kill you--if a bad decision doesn't get you first.
My brother died of alcoholism two years ago. He only drank wine.
