Husband cannot wake up

My husband has long bouts of sleeping (18-72 hours at a time) always preceded by a headache in forehead area. He says that the headache is not real painful but more like a pressure. He also has cirrhosis. He tested borderline at the sleep disorder clinic. He has had these bouts of oversleeping for the past 6 months. He also has severe confusion at times.
