Wanna change my antidepressant remeron (mirtazapine) to something similar will i have trouble changing this and what antidepressants are similar ?

Why?: "If you want something SIMILAR, why do you want to change?"would be my question. What do you NOT like about Remeron (mirtazapine)? Is there something in particular you feel it is doing to you that it shouldn't, or something it should be doing that it's not doing? Or both? Think about these questions, write it all down (because you WILL forget), and bring it with you to your prescriber. Together decide what next
