I need some medical advice. I take Zyprexa for symptoms of schizophrenia. It works fine for the symptoms of schizophrenia but it makes me lose half my day by making me sleep until 11 am. I try to take coffee, which should be enough, but I still go back to sleep. Then once I'm awake I can't study effectively because I feel weird brain fog. Should I just drink more coffee or switch medications?
