Same my doc kept giving me one week samples. I've had a good experience with it so far. Only problem when I was at 80 mg, my tongue became "slow" and I kept clenching my jaw and biting my tongue. After telling my pdoc this (how she knows it was Latuda from the other meds dunno) she scaled it back to 60 and those side effects are minimal at most now.
It is also suppose to help with bipolar depression, although I'm not sure if it has in my case. I mean now I'm not suicidal, not crying as often, not feeling as hopeless but I have moments where all I do is stay in bed. But then again that's why I'm on 2 antidepressants too.
