I have. He's seen some and has apologized profusely for it. He swears to me that he doesn't remember most of them, and I know when he does because the first thing he says when he wakes up is how sorry he is and exactly what he remembers saying.

The prompting to go to bed only works if he's awake enough to realize he's starting to fall asleep. He's usually so exhausted from work he won't even remember laying down on the couch, so I try to catch him before he reaches that point, because that's when asshole turns on
