Hi,
It took me a while to get the right system- I use Hollister. The stuff they put on in the hospital was terrible; big clip and clear bag. Yuck. Now I use the "lock and roll" bag which has a velcro closure. I tried the bag with the filter because I like to drink carbonated water but I found that the pressure of the underwear pushed the filter part right onto the stoma and that hurt like hell. Plus I found it didn't really do what it was supposed to.
I have always emptied at least 10 times per day but that's partly because I'm paranoid about leaks and because my ileo is so high that it's liquid all the time. By the way, I tape around the flange so that if a leak is threatening, I can usually feel it creeping and get to it in time.
