I couldn't tolerate Latuda, so don't have any feedback on that.

Seroquel works well as a sleep aid at lower doses, but loses a lot of those properties at higher doses. For me, it works well to regulate sleep without knocking me out. I'm on 200 mg morning and night. It works well for my anxiety and mania but did nothing for my depression. My pdoc added Abilify for depression, which usually works decently.
