I didn’t like Latuda. It didn’t sedate me enough.
Does it keep your positive symptoms under control? If so, give it a chance.
About the sleep: try trazodone or melatonin or magnesium if Latuda works. Maybe even Valeria root. Those worked for me.
I never had nausea or vomiting on Latuda. That’s strange. Bring it up with your doctor.
I just remember having headaches.
