If it bothers you, talk to her about it!

Otherwise, a therapist doesn't necessarily have to follow what they tell their clients to do - if they dont think they have a problem or whatever, then they're not really bound by the same "rules" they might set for their clients.

What bothers you about her telling you not to drink, and the fact she was drinking?

Do YOU think you're seeing a substance abuse T because you feel you have a problem? Or do you think you don't have a problem?

I know its sometimes unsettling to see a therapist outside of the therapy context as well.
