I didn't have neck problems until I raised the bed to help with the reflux. Now that I have lost lots of weight the reflux has disappeared so made the bed level again and my neck problem is slowly getting better.
I figured it was the tight headgear straps that caused the neck problem. The raised bed seems to make more sense to me when I think about it.
I am the inventor of the U Sleepwell sleep positioning system. It is an Inclined lateral sleep positioning system. I have been using this system for the last 4 years with very good success. take e a loom at my website www.u-sleepwell.com, watch the video on my 'About us' page.
I placed the pillow down to my shoulder blades for a few nights until I noticed low back twinges. Now I just adjust a cervical pillow to prop my neck in slight hyperextension. It seems that if I don't drop my jaw down, my AHI is lower. Since I started this a few months ago, I have had 14 zero AHI readings (pre-treatment AHI was 49 with desats to the 60s). My husband has benefited from this wedge positioning, even sleeping on a slight wedge pillow. However, he side sleeps and changes position frequently, so the wedge does not bother his low back.
