i wouldnt' go back to life without one either! this is so much easier. this is an odd thing, but we were out with friends the other day and one of them had to go poo the normal way, and so they were gone for a while, and i thought, wow i sure dont' miss that!
you don't have to change your clothes, you dont' have to change the way you sleep, i just snaked some of those pads from the hospital, the waterproof ones they put under you, sewed a sheet on top of them, and sleep on them. That way, if i do have a leak, all i gotta do is get up, take off the pad and change my stuff. Not change the whole bed. I also already had plastic covers on my matress, i have a small child, lol. And that makes me feel better. It doesn't keep you from doing anything, or make it harder to do anything.
I won't lie, there are times when it's a bit annoying, but then i think, you know if not for this, i would be sitting at home still, instead of doing all the stuff i have been doing lately! since i got mine, i have gotten some friends, i go out every friday night, my friends and their kids come over and we do stuff, like swim, and bowl. I actually just came home from their house. Could have never done that with UC.
Could it leak? sure it could. But if you think about it this way, it's in the front, and you will know really quicly if it happens, and most people are not gonna think that it's poo in the front anyway, so just run off to the bathroom really quickly. There are things you can do to help keep leaks at bay, and never change right before leaving the house, lol. I have changed and run out a few times, but for the most part i like to change a few hours before i am going to go somewhere.
For showering and swimming i tape the bag up on itself so that it wont' show or get in the way.
Good luck with your surgery, and keep repeating this, "I wont' be sick, i won't be sick!" Also make you a list of all the things you CAN'T do now, and then make a list of the things you think you won't like about the bag. I think you will be suprised how much bigger the first list is.
