Am I an alcoholic?

I drink everyday, pretty much without exception. Not over the top but like 4 beers or a 3/4 a bottle of wine or some whiskey/scotch depending on my mood. I feel the need to drink everynight, but it doesn't affect my day. I always feel fine when I go to work and do my job. I'm the same way with ciggerettes, I don't smoke all day, I don't even think about it. When I get home I crave a cigg. I usually smoke 4 or 5 a night. 2 packs a week (more on weekends). Ive asked my freinds, who tend to drink more than me when we go out and none of them drink during the week like I do. I've been doing this for years, and was surprised recently to find out none of my friends drink during the week they wait for the weekends. And just to help you answer Im in my mid 20's not some 18yo.
