Hi dprovan!
Well, I have read numerous times that if you think you have a problem, you probably do. You might ask yourself what alcohol does for you. And, very importantly, IMHO, once you start drinking, do you feel a compulsion to drink more? Is your consumption affecting your life negatively? You sound as if you can take it or leave it, but under social pressure (and maybe just because this is your habit), it seems foreign to live without alcohol. I guess, for your own peace of mind (because of your concern about your inclinations), why not give it 6 months and then reevaluate. If you can live without it, why do it?
