I did it and it confirmed what I found out the hard way: that SSRIs don't work as well for me as SNRIs (serotonin neurepinephrine reuptake inhibitors). Have you ever tried an SNRI? I'm on Cymbalta now and it works better and has fewer side effects than SSRIs.

GeneSight does tell which meds may cause potential side effects. It's not perfect, but it's better than blind guessing.
