Could it be possible that you need one of these antipsychotics, yet take another drug to counterarrest the side effects of the antipsychotic? There are many, many drugs out there that help with the side effects of APs. For example, there are particular medicines that help with akathisia. I don't know of many medicines that counterract weight gain or anything like that unfortunately. I am currently taking lurasidone which helps my psychosis a lot (pretty sure that's Latuda in the U.S.), but I saw that you mentioned that one gave you akathisia. Have you mentioned any of this to your prescriber? Perhaps that person could help orient you around which antipsychotic to take if you express your concerns. And also, maybe they can suggest an adjunct medicine to help with the side effects from the AP.
