Hi Mary,
Welcome to AHC. Hello to you, Gus, and Foxman, too! I tried moderation so hard, Mary, and in the end, realized that moderation was harder than quitting altogether for me. You can read my trials and tribulations with moderation here on the forum under "I need support from you all" in the introductions section. It chronicles a year or so of my journey to becoming sober, with all the bumps in the road along the way.
There are people who successfully moderate, I just wasn't one of them. I didn't drink every day, was fully functioning, and still don't consider myself an alcoholic, haha! I just don't drink anymore. I didn't go to AA, never did an online program, I just got advice from the folks on this site, and paved my own road to sobriety. It wasn't easy, but eventually I got to a place where I just don't drink anymore. It feels great to not have hangovers, to not have fluctuations in my moods from drinking, and I certainly don't miss the shame and embarrassment that came with being too tipsy.
There are many ways to moderate, or quit drinking, and by admitting you feel your drinking has become an issue for you, you've already taken the first step. I posted a lot in the beginning, and received a lot of help here. I wish you all the best.
