I am kind of like you nathan123 in that i also got an ostomy at 24, which was a colostomy for me, but has turned out to be permanent. But unlike you I knew nothing about ostomies before hand and struggled with managing it for a solid year and a half before I learned about Irrigation. I have been Irrigating for over 6 months now and it is in my opinion hands down the best system! I iririgate daily, though i dont necessarily follow a "set" time, due to my work schedule and busy life. None the less it lets me 99% of the time have an empty pouch and significantly less gas then just wearing a system and not irrigating. And even if i do have a little bit after the fact, once in a blue moon, it is never much and i find it overall gives me MUCH MUCH more freedom and self confidence, especially being in sales and interacting with new people face to face, day in and day out.... Even when traveling! :)
I know they say its "important" to have a specific time to do it every day or 2nd day, but i find that even if i have to irrigate one day in the morning and one day in the evening, overall my movements are regulated by the irrigation process *unless i eat a huge amount more one day or some foods i know cause issues like really spicey food, which is best to avoid regardless*.
My best advice to you with finding out if irrigation is right for you would be to stick with it for atleast a few months after you start. With time you should find that the 1-2hrs a day max or every other day set aside for it, will not only free up time throughout the day with bag changes and/or quick bathroom breaks, but will also drasticaly increase your confidence not having to worry about your pouch when your out and about doing your thing.
Because IMO atleast for me, going about your day all day with a pouch that's filling up and or partly full, as well as your bowel always having a mind of its own can be the most annoying and sometimes uncomfortable thing in the world, ESPECIALLY in public.
One thing to keep in mind, which atleast happened for me, is that initially the results vary. I found that it also worked right off the bat for myself, but after a few weeks it seemed to not work so well for some odd reason *no diet changes*. But I stuck with it and over time my system was properly trained. The amount of water and frequency between days is simply all the little things you will sort out that work for you. Starting out i was able to go 3, even 4 days between flushing with 1.5L. But now every day or early other day with 1.5L seems to work best for me and gives me complete peace of mind.
