Welcome Gomez, glad you're here.
You're not sure if you're an alcoholic? I've learned in the last two years that if you even think you might be an alcoholic, you're an alcoholic. Sorta like "looks like a duck, quacks like a duck, so it must be a duck". Normal drinkers don't even question alcoholism, it simply isn't an issue for them.
For me, it wasn't how much I drank, it was the mental obsession that compelled me to drink until I was drunk. It's the first drink, not the 12th that kicks the obsession into gear. You don't need to be a daily drinker to be an alcoholic.
I had a wife who thought I had a drinking problem. I say "had" because she's gone now, and so is the home and family we had together. It's not too late to achieve sobriety. Nobody ever died from NOT taking a drink, but there are plenty of good people who are no longer here because they chose their addictions.
