Hi Allstar,
Welcome!
If you start drinking and you can't stop, then you have a problem. It sounds like alcohol is causing problems in your life. Alcohol is a depressant, and if you are already depressed, the alcohol will make it worse and it can diminish the effectiveness of your medication. When you stopped drinking for 9 months, what other changes did you make in your life? I believe that drinking is a symptom of the problems we have in our lives and it's after stopping drinking that the hard work begins.
I hope you take a look around and read and learn.
