It sounds like the situation has become pretty polarized. For me, I would break that by trying T's way for a certain period of time to see what it was like. I'd decide to give it a 3-6 month trial and then see how I feel. You can always go back to drinking, wean off the medicine or try different ones, etc.

Other scenarios do not look as bright to me; T cannot stop telling you what she thinks would be more healthy for you, that would be unconscionable behavior on her part? All she can do is not be able to see you anymore because you are at a true impasse where the reason you have hired her, she cannot help you with because you have chosen not to work with her.
