question: My nephew 25 yrs old just diagnosed of schizophrenia, started zyprexa 10mg yesterday. He did not sleep well for a week even with ambien . He slept 14 hours last night. He still felt tired this afternoon & went to sleep 7 hours after getting up. How long do we need to wait to see his symptoms( hallucination) getting better after the med. Any other treatment does he need ?
