Your pdoc might not prescribe you sleeping meds. My psychiatrist says that sleeping meds and psychostimulants like adderall are a big no for schizophrenics because it increases hallucinations. Since you're in a manic episode it could be very bad for you. Take melatonin instead (mine said about 3mg is good, but ask your pdoc) and I've had pretty good luck with zzquil so you could try that.
