Hello Michelle,
All good comments. When I first got mine, my wife changed the pouch for me with me on the bed.
after about a year, I started doing it myself at the sink, i put down an old towel on the floor, and several kleenex close. I use the Holister one piece, and change it once a week. I also use the skin prep.
a hair drier is your best friend, i take a shower most days, and just dry the tape well. I also useit to dry the skin when changing. On changing day i always take a shower without the pouch.
I also wear an elastic belt, I don't know if it helps, but I feel more comfortable.
I empty it often, sometimes i kneel, othertimes I scoot back and empty it between my legs. I always put toilet paper on the rim to make sure none gets on the rim, and it seems to make it flush better. As mentioned, get the toilet paper to clean the drain portion before you open the clip.
Make sure the clip closes correctly and repace it often. The Hollisters I use come in a box of 5 and a clip with each box, I use the new one. The only real messy accidents have been when a clip breaks or comes unsnapped. The leaks happen, but usually aren't to noticable to others.
If you are like most of us you will soon be thinking less about the pouch and more about living normal. I know you don't feel like it now, but in 6 months you will be living a much more normal life than you had with UC. I remember planning my day around the nearest restroom, and that was 25 years ago.
My recomendation on gas is keep a log of what you eat and how much gas. Also some things you should avoid. For me it is nuts and sourkraut.
Feel free to ask anything
Glenn
