doc, i use hollister's smallest drainable bag all the time. (except when i had the flu, then i switched to a large bag) i average 7 empty's in a 24 hr period. at night i sleep for two hrs, wake up, empty, then go back to sleep for 6hrs straight. then i have to empty again when i wake up. i wake up after the two hours because i have to pee, not because i need to empty, but i figure since i'm up anyway i'll empty the bag. i think most everyone empty's when they need to pee, i mean you're in the bathroom anyways, might as well take care of alllll your business!! as soon as i get to bed i fall asleep right away, no problems there.
as for gas, the bags with filters work great until they get plugged, which is usually the first time you lie down or take a shower after installing the bag. (i've only used hollister so far...) which means that for the remainder of the time you wear that bag, yeah you'll need to "burp" the gas out, IF you have gas. that means separating the bag from the flange in one area for 1 second while you squeeze the bag to get the gas out. NOTE: do this standing up, if you do it lying down you'll get feces squirted on your chest. that's right, that's EXPERIENCE talking, ha!! after a while you'll get the hang of it, i burp the gas under my shirt while walking up the stairs. you'll learn how to do it and it'll become automatic--no big deal.
i would think everyone is differnet with their output levels as well..maybe some others can post up
