Welcome Etta and InAHole-you will find comfort and help here and glad you found your way to SR.
I'm quitting for many of the same reasons you're thinking about it. While nothing dramatic happened to me either, I felt the same downward spiral, losing my drive at work, going through the motions, stressed out, tired, and worried about my drinking getting worse with severe consequences. I can honestly say that even though it's only been 5 weeks I feel so much more at peace with myself. Drinking was causing most of the anxiety I was feeling, I think.
I couldn't look at it as stopping forever either because it was so overwhelming. All I can do is say "not today" and it's working so far. Not for today is manageable. It makes me feel like it's still my choice, even though I know booze has to be out of my life. I come here often, and it truly helps. Best of luck in the beginning of your journeys!
