When I go about my day padded, I find that I have the urge to urinate more often than when I don't wear, regardless of fluid intake. At work, while in "big boy" undies, I rarely need to step out to the bathroom, maybe once on a full 8 or 9 hour shift. While wearing goodnites? Almost every 15 minutes. Even on a short mid shift(4 hours) I had to step out and change, once about halfway through, and again after I was done. Other diapers have the same effect, but naturally don't need quite as many changes. Pavlovian conditioning maybe? Subconscious response to wearing diapers? I don't know. It is interesting though. I may keep an I/O sheet on myself just for kicks.
