I would think it would be difficult to prevent sleeping on your side unless your body was physically immobilized. Rather than trying to physically avoid the symptom, why not try to "heal" the symptom. For spondylolisthesis of the lumbar spine, physical therapy may be helpful. Have you, as yet, consulted with a physical therapist regarding treatment for that condition? This would be my suggestion. ..Maurice.
