Welcome Stu! I wish I'd done what you're doing at age 30. I could have avoided so much misery. If you are an alcoholic (and only you can really know) please remember it's a progressive disease. I was still in control at your age, but by 50 I was drinking 'round the clock. I never dreamed I'd ever allow that to happen. So, you are wise to be cautious.
We are here for you. You'll find all sorts of wisdom and good suggestions. Congratulations for taking this brave step.
