Hi...Did doctor gave you any diagnosis? Is it Schizophrenia? If yes, then the medication is fine. Audio Hallucinations are very common in Schizophrenia. Sleepiness is one of the side effects of this medication. Actually this medication restores the chemical imbalance in the brain, to address the disorder of thought, emotion, and behaviour which is altered by the illness. Try visiting another Psychiatrist for second opinion. Dr Naveen Jayaram is a good Psychiatrist in Bangalore. You can search him on Google and Practo.
