Yes, I sleep on my stomach, and you can, too! I always empty before I go to bed, and then, I lay on my stomach and bend my right leg and hug a pillow on my right side, which lifts that side up a bit. It's so comfy. Give it a try!
Dx'd Crohn's in '99 at age 28. Proctocolectomy and permanent ileostomy in '06.
Disease-free and medicine-free since surgery and very thankful to be healthy again.
