My oldest brother, was first DXed Schizophrenic when he suddenly crumbled, no longer the person we knew, this was in the early 60's and had been given many of the meds you mention, made matters worse, Lithium was a Godsend, he has been on it for over 30 years, after an excellent pdoc mde the correct Dx, Bipolar-I.
Many years ago, the American Psychiatric Assoc. thought Schizophrenia was the "catch all label" for many disorders, it took the pdocs from Europe and other participating countries to prove and convince that the Dx's were overused, and that it was the fact many of the patients were Manic Depressive, now referred to as Bipolar, I guess the first name was too hard for the public to deal with it and asnother bad stigma for those with such disorders.
I am Bipolar - II (mild) and try to educate those that have not a clue, and so often are ready to stigmatize.
Back to the "older meds", many of them screwed my brother's mind than his actual illness, thank God for many of the newer ones. One proven thing, that Lithium has the longest track record for helping with Bipolars.
I better run, I need my sleep

I wish you luck with all of this stuff, and always remember to talk to your pdoc if your meds aren't helping or making you feel unwell, etc.

Sincerely,
DE
