I've struggled with this question a lot.
I drank heavily with xah for several years, then scaled way back to acceptable.
For awhile, I would get a drink and then smell it and not be able to drink it, so I quit entirely.
Now after many months I am ok with having a drink or two, and am not repulsed by the idea, although it still crosses my mind.
I know alcohol ruined my marriage but he has never said so, and he may never get to that point that he realizes it affected me and our ability to communicate extremely.
I will never get drunk again, or drink enough to have a hangover, or drink enough to start talking shyte.
