If anyone can help. My husbands sleep disorder seems to be ruining our marriage. He doesn't sleep sufficiently at night and by around 4 pm (on the weekends in particular), his speech becomes slurred and his behavior becomes similar to a beligerant drunk person. He is very aggitated and aggressive towards me and the kids. He cannot recognize true from false. It is scary for us. He feels terrible the next day and promises to be sure he is in bed by 11 each night. I try to regulate this and force him to bed at 11, but I can't do that every night. It is exhausting for me because I need to be up at 5 pm. When I slide, so does he and he just won't regulate himself. He also falls asleep when he is alone with the 4 year old. Last weekend, I came home from work on his day off and the front door was unloced and he was asleep in a chair while she was just left to do whatever. I can't take the behavior but if he could get it under controll, things would be better.
