Thanks, TE Marie and Saff. If I do have to go to an ileostomy, I don't want to have to worry that the bl**dy thing can fail like my j-pouch did!
Knowing how my j-pouch failure has affected me now, I wish I had just gotten an ileostomy when I was 20. Hindsight is always twenty twenty! The devastation the failure of my pouch has caused is far greater than the advantage it offered me for a few years of not having a bag. Of course I don't have a time machine, so it's all moot. My younger self would probably refuse to listen to my older self anyway :-)
