Sorry to have abandoned my post.... so much work, sigh. Thanks for your responses.
So, fingers crossed, but things seem better! My new nurse suggested I get a convatec pre cut (with convex-IT, whatever that means, but it's deeper convexity than the coloplast convex light). The first time I didn't snap the bag on correctly -- used to the coloplast which are much easier -- so I went to the bathroom in a restaurant and had output leaking on me, sigh.... but then with the second sample, I just changed today, after three days, and the seal was perfect, no leaking under the wafer at all, probably could have gone at least another day. I'm going to order some. Wearing the third sample now.
CJ wow you are in love with quite a few ostomy supplies, are they jealous of each other?
. It's good to know that cutting the tape off and replacing w/the brava strips works.... not enamored of the tape, not sure if my skin is going to like it. Do you know if it works just using sure seals? I used to do something like the trick you describe w/my old stoma, but I'd be nervous to do it w/this shorter stoma.
EQ Mom, yes, the larger wafer didn't help me at all either. I've always been a side-sleeper, so that's not enough of a fix there. But very good to know that you found something that works.
