,
I use an adjustable wedge. You can put in as much elevation as you need (up to 8 inches, or down to 2 inches). I have settled on 4 inches of elevation. A good mattress helps out a lot also. We currently have a Saatva. I can say that I am not comfortable every single night, but I do sleep most night for 7-9 hours. You can also look into an adjustable bed that can lift your upper body to make you more comfortable. There are a lot of them out there. Of course, you are restricted to what you can afford. The cheapest way to go to start, would be with a wedge. I hope you find something that works for you. I like my Laz-E-Boy recliner but am not a fan of sleeping in it. Take care and God Bless.
