I just can't imagine sleeping at that angle. Don't you feel like you are going to fall out of bed?

I'm giving this a try, and have just ordered the risers. I have such a problem with restroom runs at night, periodic acid reflux, edema, and I do have mild UARS (upper airway resistance syndrome) that does not respond to CPAP and there is not actual physical blockage. I can literally feel my throat closing when I relax enough to fall asleep—just not enough to fully close the airways like with apnea. This is only relieved by propping myself up, so I KNOW this will help. Propping myself up doesn't not do me good in the long run, though because it only raises my head or upper torso, which twists the spine too much, giving me back, neck, hip, and knee pain. I bet it's all contributing to my sleep problems. Once upon a time I tried propping the bed at an incline using blocks I found in the garage, but I never could get the bed to stay in place with my homemade risers. I think these risers will stay in place.
