If you SO falls asleep on the couch. Do you...

My husband has a tendency to fall asleep on the couch at night. We both work alot. I've attempted to leave him there once but he'll wake up at 2 am and walk back to bed. In the morning he asked why I left him there. And he wants to sleep in bed with me. If he does fall asleep he is impossible to wake up. He's such a heavy sleeper. So it's a struggle trying to get him awake to come to bed. He eventually does though lol. Does anyone else go through this? Just curious
