could the med he takes cause this? he is on Lisinopril,Atorvastatin, Amlodipine, and hydrochlorothiazide. He has almost no appetite and has lost a lot of weight especially muscle tone. He can fall asleep instantly and sleeps so heavily nothing can wake him. And if he does wake up, he is never fully awake and his personality changes, to anger, defiante, mean, very moody. But can fall asleep again instantly if left alone. He doesn't get up earlier than usual and sleeps from 8:00 pm to at least 7:00 am. His job is not stressful, we are in a rural area with little to no other problems from neighbors, traffic, etc or any other stress factors. I don't understand the need for so much sleep. If I try to carry on a conversation he cannot recall anything in the morning, says he doen't remember being moody?? We have no sex life .Please help
