You are not alone. The amount of alcohol and pot I consumed during the first years of wife's drinking is so scary I avoid thinking about it (I've got a 100 percent denial policy on this topic).
I'll tell you one thing, if I had the money I spent on both between 1998 and 2005, I'd be living pretty large today. Control freak that I am, the moment I realized I was too drunk and stoned to control things the way I wanted, I stopped.
That's when I learned that I can't control things the way I want sober either. That pissed me off, but it also got me moving the right direction in my own
Al-Anon recovery.
Take what you want and leave the rest,

P.s. I did all this without a physical compulsion to drink and smoke. It was all emotional and psychological for me and I'm very lucky. Had I the physical propensity I'm fairly certain I'd be dead right now, and I'm certain I wouldn't have been able to simply stop.
