Living with Sleep Disorders

I am at my wits end with my husband. Mind you, he has not seen any doctors yet, but I was wondering if anyone has any input for me. For the past 7 years I have been dealing with my husbands sleeping problems. He has a huge snoring issue for one. I cannot say I specifically notice apnea although there are moments where he will get quite and then snore even louder. He has never woken up to get air that he has remembered or that I have seen. The problem that is even bigger is that he cannot wake up in the morning. No matter what I do he cannot get up. He doesn’t hear alarm clocks. I wake him 10-20 times and it can take up to 1hour or more until he finally gets up. It does not matter what time he goes to bed. He does no complain of daytime sleepiness. He has always preferred night activities to day. He has tried going to bed early but it doesn’t help. He says that sometimes he wakes up on his own early and feels good but if he lays there for any length of time he falls right back to sleep. Weekends are a nightmare. He can sleep all day. Noon and later are often when he gets up. If he gets up and comes downstairs at a reasonable hour, he will sit on the couch and doze off a million times. When I wake him and tell him he is snoring, he tells me he wasn’t sleeping or wakes right up but falls back to sleep within a few minutes. This can go on all day. If he gets up and is productive, there is no stopping him. I just can’t understand all this. I have a 2 year old and a 4 year old so you can imagine my anger when I do not get help. They also see this problem and my anger. My husband says his father was the same way and his mother had to constantly fight with him to get up in the morning. That doesn’t make it right. Can someone give me some insight into this and where should I begin in getting him some help? I love my husband dearly but the strain it is putting on me is becoming to much to bare and I don’t want the animosity it is creating to ruin our relationship. Please help!
