My husband falls asleep almost immediately after his evening meal. It's something he's always done on and off but recently it has become a great deal worse. He fell asleep hold a slice of pizza and food in his mouth a few days ago. Once he's asleep I cannot wake him, even if he speaks to me he doesn't remember. He always eats late in the evening rarely has breakfast of lunch. Can anyone give me an idea of what this may be, he hasn't been to bed of his own choosing for almost 3 weeks as I have to leave him on the sofa.Help!
