But that's not a dozen drugs

That's true, I missed the sentence about a dozen drugs. Keep in mind though she might not take all of them exclusively for that particular condition.

I can think of a half-dozen neurochemicals she might be pioneering

I would be interested if you named a few, and whether there's any evidence of their usefulness.

I can think of a half-dozen neurochemicals she might be pioneering.

If that's the case the question becomes should she really be allowed to do that. I have no problem with that if the system allows for the patient being completely responsible for taking those drugs, but I don't think any doctor or insurance company should be expected to take the fall for her. If the drug isn't well documented and she doesn't take part in a trial, I think she should finance treatment for any complications herself, and that could easily get more expensive than she can afford.
