I second this ^
I don't know what your relationship to alcohol is (aside from the fact that you've got a desire to give it up), but I've wrestled with the sauce myself for more than a decade (I'll be 29 in a few weeks). My longest streak of sobriety was something like 1.5 years. I put it down again about a month ago, after letting myself drink for a little over a year, and am feeling happy about it. We'll see what happens...
Usually I end up quitting because my body rebels against me, I've hurt somebody, or some combination of the two. My vanity makes it difficult to walk around looking bloated all the time, and my integrity/empathy (when available) make it difficult to be an asshole to the people I share my life with.
When I start drinking again, it's usually because I get nostalgic for the act, or the "sport" of drinking, or because I've deceived myself into thinking that I've become more mature, or have more self control, or I just want to lay claim to some agency or personal freedom or some other mystified bullshit.
At any rate, I'm sure you're in good company. This is probably the first time I've posted about my issues with drinking (I thank you for opening the space to do so), but I can recall reading a bunch of posts from others on this topic in the past.
Sober living can be tough. But if your experience is anything like mine, you've got a a lot of room to grow, and that should prove really rewarding.
*EDIT - pugmaster, your reservations about AA are justified in my eyes. I've been a couple of times and something about the whole thing was very off-putting. I couldn't justify going into a group where people are encouraged to obsess recurrently over their addictions and personal shortcomings. I'm something of a hermit, though, sober or otherwise, so my perspective is limited.
