Hello mimi,
I don't understand. Did you have your three kids before you started taking the schizophrenia meds?
Everyone I know who discontinues his or her anti-psychotic drug ultimately relapses and has to be hospitalized.
Yet the truth is, women with schizophrenia who are taking anti-psychotics have gotten pregnant and carried a baby to term and given birth and are now raising their children.
You have to talk to your doctor and see how it's possible to do this, because I don't know the specifics.
From this second question, it seems your doctor is resistant to work with you during a potential pregnancy.
It has been done, I just don't know the details of how you would do it, and you should talk to your doctor or get a second opinion.
Regards,
Chris
