How to wake an incredibly hard to wake person?

[Swtandrea2]

My husband is 35 years old and since he was a kid he’s had this problem of not being able to wake up in the morning and from naps. It can take more than an hour (many times longer). Alarms do nothing or he just turns them off. I’ve tried everything. We have about 4+ alarms that go off (nothing happens)  I say it’s time to get up (nothing). I make him coffee (nothing). Sometimes his eyes will open or he moves his feet but he does not get up. After awhile of trying, removing pillows, removing blankets, shaking, begging, it turns me to screaming and fighting which makes it worst. He gets mad. I have physically pushed him off the bed and he will just sleep with legs on the floor or his whole body. I’ve even blasted stupid songs and sang them loudly with him only getting mad not up. I’m so frustrated, I’ve been dealing with this for 20 years, his parents stopped sending him to school as a kid because they were tired of dealing with it. We recently tried an alarm that stimulates the sun rising and that only worked for 2 days and then he’d sleep through it or turn it off. And it’s not just at night, he can fall asleep within minutes in the afternoon for a “quick nap” and can’t wake up even if it’s been an hour or less. And if you leave him he could and has slept all day. Someone please help me, I’m loosing my mind. I’ve asked him to look into sleep specialist but he doesn’t care. This problem has affected our family, our marriage and his personal life. He’s missed appointments, work, and there are times when sleeping for 10+ hours still doesn’t work. This is a daily occurrence, every morning the kids hear me scream, they see me loosing it and him just sleeping. Right now as I write this he’s sleeping with every light in the room in and he’s had 6 alarms go off including me calling his phone, coffee is now cold, he’s woken to pet the dogs and then fell back asleep instantly.
