I have been taking Mirtazapine for my Depression disorder and sleep disorder for nearly a year, it's side effects of bad dreams and dizziness are beginning to be really bothersome. I am looking for an alternative medication so I can go off of this. I have been diagnosed with Bipolar as well, so I assume I need a seratonin reuptake inhibitor. I have tried other medications on the reuptake inhibitor list that I had severe side effects and could no longer take. I appreciate any input here, thank you in advance.
