Chances are there's something going on in your life that you want/need to get away from, that's scary or very uncomfortable. It may or may not have anything to do with your bipolar. But your mind would rather smother this something in alcohol than let it come into your consciousness.

Whatever it is, your unconscious thinks it's threatening. It may or may not be threatening in reality. But that desire for alcohol is there for a purpose. It didn't just spring up from the ground by itself. So what you need to do is think a lot about your current situation, at work, at home, with spouse, with kids, about money, about relatives, about your own mind, that may possibly be bothering your unconscious.

When you find it, you need to solve it in some way that makes your unconscious happier. Then the desire for alcohol will go away. If you don't have a T now, you may need to get a T for this. If you do have a T, it's something you have to talk over with him/her. Your desire for alcohol is a sign that something's wrong somewhere. Your job is to find out what and fix it. Take care!
