Welcome to Healing Well. Sorry to hear you're having trouble.
I live in Florida, so I can't stop by to help, but I'll do my best from here. Have you tried putting the wafer on while laying flat on your back? If you get it to stick while your belly is flat, maybe it'll stay on better once you stand up. I use Coloplast Extended Wear Wafers, and they stick really well, so you might want to give them a try.
Dx'd Crohn's in '99 at 28. Proctocolectomy and ileostomy in '06.
Disease-free, medicine-free, and very thankful to be healthy again :)
