Yeah I'm with Adami, being in the same/related professional field.
Addiction in its many forms is not really a moderation game. Especially if it's "depressed drinking" as JayO said, vs. "social" drinking. For someone in addiction, having a few is not a good long-term healthy option. And addiction isn't limited to just booze, street drugs, caffeine, gambling and tobacco. It permeates into many other realms, with gambling being an example. I also extend using unhealthy coping to beyond addiction, and to procrastination and trying to ignore problems via doing something else. And the unhealthy things we pick often activate the fun brain chemicals more effectively.
An internal bargaining process begins as I tell my clients/patients. For example; (self talk) time 1- just one beer, you deserve it. Really hard day, real hard event. That's it. 2- dude, that beer was awesome the other day. I bet having two will makes things even easier, and better. Then that's it. 3-well hey, I did fine with those two. Johnny has some weed, how about a coupe of beers and weed?
It then goes on and on. If someone can manage it, drink whatever amount, then deal with the problem. Then deal with the problem more.
I do not think Adami was getting at being judgmental about JayO's drinking, or the act of drinking anyway.
