I have a whole year that I don't remember most of. My p-doc was changing my meds every two weeks. It was horrible. I did end up firing said p-doc for incompetence but that was because I had an allergic reaction to a medication so he decided to leave me unmedicated until our next appointment. Like Perna said, sometimes it's just trial and error. But, be your own advocate or find someone to help you advocate for the treatment you need.
