take some gas-x before you leave your house, dont let yourself get hungry.
And i do what Ron said, only i take two small pieces of towels that i have cut up and put them right over the stoma area of my bag.
If im out and dont have those and it starts getting noisy, i fold up some toiletpaper and put it in there. Also those geltabs help with the noise too.
UC for 8 years, before finally kicking its butt and having a permanent ileostomy April 17 2007!
-I have gone to find myself, if i get back before i return, keep me here-
