Hi,
Welcome!
I'm not clear on my understanding of the bipolar medication you're taking. Is it helping with the depression? If not, I suggest going back to your dr and consider trying something different because different medications work differently in each of us.
I found that I could never limit or control my drinking, at least not for very long. If you are an alcoholic, stopping drinking completely, is the answer. It was actually a relief for me to just stop. There are other ways to handle life's problems than with drinking, and we're here to offer support to you.
Addiction is a very isolating disease. When I finally stopped drinking, I had lost all my activities, all my friends and almost my family. That's what addiction does to us. But, you can change that.
