I'm on 5 psych meds because 4 weren't enough. It just works that way with some people. Nevertheless, you don't need to be on a med that a) isn't working and b) has intolerable side effects. I'm not even sure 20 mg does anything except make hair fall out.....I started out on that dose but quickly went up to 40 and then 80 mg. I lost a lot of hair too, but eventually it stopped.
