Spotted,
Whew, what a difficult situation, on so many levels. First and foremost you have the concern about Ed (now) and whether he is getting appropriate care. Then you have your own reaction to the whole scenario and exploration of that reaction with T. Clearly, it touched some sensitive spots in you. Finally, you have the decision as to whether or not you should report the doctor.
When an adult is sick with mental illness, it is a difficult situation at best. As adults, they have to make their own decisions. But if they are not making sound decisions and they are suffering it becomes so painful to sit by and idly watch. I would like to think that is what happened with Ed--that people cared about him.
Now, the whole thing about meds in the food is awful. I don't think it's legal, ethical, or conscionable.
I have an adult son who has suffered from psychosis in the past. I would NEVER sneak medication on him like that. I might nag him to death to take it, but that's another story. However, I would call his psychiatrist if I were worried about his behavior. I have called his T as well. He may not like it, but if I think he is in danger I do anyway. When I do, it is open and above board and she tells him I called.
There is a lot here for you to sort through.
