I know Seroquel is an antipsychotic and have tried it but had horrible side effects. Latuda treats Bipolar Disorder Depressive Type. I have also heard that Latuda has been taken for symptoms of Schizophrenia. I am not a doctor and am not on Seroquel or Latuda. Soooo.... this post is kind of worthless. But have been on Lithium ( I had severe tremors and made me severely depressed and eventually overdosed on it, in a suicide attempt). Valium has never done anything for me. I have Schizoaffective Disorder with the Schizophrenia usually occurring when I am hypomanic to manic. Stress will make your symptoms worse, this I know for sure. Much love and peace.
