I have OAB both bladder and bowel although I'm quite lucky that I can usually avoid messing myself but as for my bladder I will need to through being normally hydrated go to the toilet about every 45-90 minutes, I have to travel between clients with my job, if I decide to hold it, unless I get to the toilet quickly, I will feel very uncomfortable, so I just void my whole bladder, if I hold it too long anyway, I'll start peeing anyway, but by that time I'll be in pain and it's a pathway for infections.
I use the super proskins which hold 3 wettings in, I like them as a regular daytime diaper but I use pull ups if I've just come out of the shower like an hour before bed so that I don't go to bed in a wet diaper since I wake up about once or twice a night and I might need to pee if I'm taking longer to fall asleep.
I'm comfortable in them since they are descrete and distribute wetness well, the tapes are good on them and I was amazed that I didn't need to wear a big bulky diaper in order to feel comfortable during the day, I tried another diaper which was supposed to be "descrete" but it felt obvious like it made my bum look 5 times bigger than it was supposed, (I defiantly don't want that attention, thank you very much!)
