There is a big difference between wearing diapers 24/7 and using them when you want to vs. wearing 24/7 and having little to no control. In the first case, the following would apply:
1. You can moderate when and where you actually wet or mess them.
2. You can also simply remove the diaper and use the toilet if you so choose.
3. You are still paying a lot for diapers, but probably not as much as an IC person would.
4. If you are used to normal underwear, it will take some time to get used to diapers as your underwear.
5. If you wear disposables for long periods of time, be prepared for them to break apart. They are made to use and then throw away after 3 to 5 hours (when active) or about twice as long when inactive (sleeping).
6. If you live where the temperature can get over 80 degrees F, be prepared to be uncomfortably sweaty.
7. Ditto above if you are active or play sports.
8. Make sure you have a change of diapers, wipes and rash cream at hand where ever you go.
9. Be prepared for your mid-section, butt and groin to appear larger than everyone else's.
10. Never worry about waiting in line for a bathroom again (except if you need to change, of course).
The second case which many IC people know too well (and myself for the better part of 40 plus years) is the same EXCEPT you have no choice whether or not to hold it. It just happens. All the time. And, in every situation you find yourself in. I've been wearing diapers for much of my life and 24/7 for over 11 years. It can be a godsend and it can really suck. However, if you are curious about wearing diapers 24/7, just do it. You may find it to be terribly inconvenient or exactly what you were looking for.
