For silent reflux it is recommended that you sleep at a 30 degree incline (or more). This may be a silly question, but as a side sleeper how do I keep from sliding down? I have some plastic wedge risers under the mattress that are about 5 inches high and I still slide to the flat part of the bed-even though that is not even thirty degrees. The wedge pillows did not work for me. My throat definitely hurts more when reclining.

Thank you for any tips!
