But this:
> They would have discontinued the medication, terminated the doctor patient relationship, then waited for things to "go back to normal" when they were off the drug but found it never did.
is not the way a good psychiatry practice (like the one I frequent, IMO) is designed to work. You try a lot of different things and you see what works. You're told upfront that this is part of the process and that if you don't like a medication, you don't have to keep taking it, and you should tell the doctor why and what you're open to trying next.
I tried buspirone (which I still take), duloxetine (intolerable GI side effects; didn't take for long enough to experience anything sexual), and bupropion (too stimulating, not right for my condition) before I settled on citalopram. I had been specifically avoiding citalopram because I was scared of it, and I feel a little foolish for that now.
So I think your scenario is unlikely in my case. I can't speak for other doctors.
