You are so wise and so lucky to be thinking of this in your 30's. I am like doggonecarl, and waited until I was much older to get sober. Please believe us when we say the disease is progressive. We alcoholics have many regrets.....But my biggest regret is not paying attention in my 30's to that nagging voice that was surely telling me I had a problem.
This may sound cliche', but a sober life is a beautiful life! Good luck!
