Normie,
There's really nothing in your post and your description that indicates one way or the other. I think it's good that you are questioning it. It sounds to me (meaning just my opinion, take it or leave it) like IF you are alcoholic, you don't really have a 1st Step experience.
You can try drinking (scary) and see how you respond, OR you can go back to the Big Book and study the Dr.'s Opinion and first 3 chapters.
I personally can't imagine being around AA for 5 years and not knowing the facts about myself. Find out the facts. Because if you are alcoholic, you are a ticking time bomb without those facts.
