I was on antidepressants when I first started AA because I was depressed. They are a prescribed non-addictive medication without which I doubt whether I would still be here at all. I was able to come off them after a few months sober under medical supervision. I do not believe they have anything to do with my sobriety date. I wouldn't hesitate to go back on them if I became depressed again.
It doesn't matter to me what other people take. It doesn't even concern me if people still drink and lie about their sobriety. That's their business and its their journey to make.
The only thing I'm concerned about is my own journey and being true to myself. And AA has helped keep me sober for many months now.
Don't concern yourself with the rights and wrongs of other people's actions. Look to yourself and how to work the program to get well.
Best wishes to you x
