I had a few stints of 24/7 once I started a full WFH job. I decided to go all-in on the lifestyle choice. While I didn't have a goal of losing control, I didn't make any conscious effort to preserve it and knew that could be a likely outcome.
I decided that I was going to use diapers as diapers rather than as a fetish item. I like diapers but I really wanted to incorporate them into my life in a more utilitarian way. I decided to wear 24/7 with no exceptions except the shower. The biggest rule was no holding, no forcing. Any time I realized I need to pee, I'd let go and allow it to happen. Doesn't matter if I'm in a meeting, at the supermarket, or anything else. Same for poop- I made no conscious effort to hold it and instead let my body decide what to do with it. Nighttime was a little trickier because I'd wake up to pee, but I just made an effort to relax and let it flow without moving or thinking and fall right back asleep.
What surprised me was just how fast my body adapted to this new lifestyle. I never wet my diaper without realizing it, but it took about two weeks for my body to just let pee go without asking me permission first. Shortly after that I started waking up with a wet diaper too! It's entirely possible I was waking up and wetting but not waking up enough to remember, but that might as well be the same thing. I never got to that point with pooping but I did reach the point of noticing I needed to go any my body not trying to hold it back.
Ultimately this lasted about three or four weeks before I stopped. There were a few challenges. The biggest was that I have really sensitive skin that doesn't like being diapered all the time with pee/poop held up. I started doing small, frequent micro-pees and didn't have the budget to change every single time, and my skin paid the price.
It was also a huge lifestyle drag. I do a lot of hiking which isn't a diaper-friendly activity. I go to the gym 4-5× a week and I'm really attached to my routine; wearing diapers is a major problem when I like to change before and after my workout. I also go camping with my wife a lot and don't always have fast, easy access to a shower. And wearing diapers means needing to shower like 4-6 times a day (I'm not great at cleaning myself with wipes alone). I also like wearing bikinis at the beach, going clubbing, and have a lot of other activities that make diapers either a functional problem or impossible to hide.
If something changed in my life and I had a full-time caregiver I'd strongly consider going back into diapers permanently, but I'd need them to really be all-in on supporting me in that lifestyle. I don't have that so considering it is neither here nor there.
