Hi ladies - I have been irrigating my colostomy for over 3 years now, every day. I've never been able to make it to the every-other-day schedule like some of the men on this site, mainly I think because they eat a real low-fiber diet, and I like things like salad and fruit and other stuff that has fiber.
At first, it took me an hour to irrigate, but now on a good day, I am down to 25 minutes (that's if I haven't done something dumb the day before like eat a lot of pasta or pizza, both of which seem to stop me up). It's really important to go slow at first, though, and NEVER try it the first time alone (make an appointment with a WOCN at your nearby hospital).
Going slow will keep you from getting nauseated or having accidents and wanting to give up.
I use Hollister ostomy products, but I don't like their irrigator bag, so I use the Coloplast bag. It has an adjustable water wheel to help you see how fast the water is going in, also a built-in temperature gauge so the water is not too hot or too cool. It's also a lot easier to fill. But you MUST order the irrigation SLEEVE that goes with your ostomy supplies.
As for traveling - I have irrigated just fine in the US, but would be careful overseas to only use completely safe water, such as bottled water or perhaps boiled and cooled water. If you introduce parasites or bacteria into your colon, you may get Montezuma's Revenge wherever you are. Also, only drink bottled water or other beverages.
Sometimes when I have a bad day, and I have unforeseen problems, like eating the wrong thing and it blasts through my system, and I have to empty or change my pouch, I think of people who have to do this all day long and I THANK GOD I am able to irrigate! ;
