Do I have an alcohol problem?

I work as a translator and my job is quite stressful and I usually work long hours. Also, I have some trouble with the neighbours, who are the intervening and extremely curious type and some other problems. Sometimes I have a bottle of wine or cheap sparkling wine with juice in the evening to calm down. Lately, it's been one bottle a day and I'm a bit worried. If I don't have any, I'm okay, just less calm, sometimes I get upset and cry, thinking of urgent jobs or people who put pressure on me. As it's "only" wine, it doesn't affect my work, since it's not in the blood anymore in the morning, but I hate being dumbed down in the evening, because it prevents me from doing things I like, like painting or writing. I feel like taking a half year break, but I can't afford it, therefore sometimes it seems the easiest way to calm down. What should I do?
