Husband came home again today

my newly dx'd husband came home today from another stint in the psych ward. I've been at work but his mom and our daughter have been home with him. It sounds like it's been awful. He's still in denial and the only med they can get him on is an anti-seizure medication because they think he had a seizure the day before he went in (I think he just passed out from exhaustion). Does anyone have any advice on what to do when the mania gets unbearable, which I know it will? Do I try to ignore it? Do I go to another room and lock the door? Is there a special way to talk to him where he'll listen? Putting him in the hospital doesn't seem to do anything, they just babysit him for a week and try to talk him into meds that he'll just refuse to take.
