I may get my head ripped off for saying this but in your state/country can you procure legal cannabis with a prescription? Get it on the black market if not. I know when I would very occasionaly smoke a joint in my drinking days I be disgusted at the idea of having a drink. I remember having a sip of my favourite beer and I physically spat it out. I also know of a man who is now sober after over 15 years of heavy drinking, he got sober by smoking cannabis (illegally), he said it still wasn't an easy road but it worked a treat for him. Of course then you have to stop smoking cannabis when you get sober, that may be hard for some.
If you have tried all of those (in my opinion) amazing drugs then maybe it really is worth a shot. If you don't like smoking you can always cook it into cookies, cakes etc.
No offence to anyone, but I attended 4 AA meetings, I really didn't see how they would ever help me give up drinking. It just wasn't for me, I felt depressed afterwards to be honest.
