The struggle with tabs has prevented me from using those types of diapers. I now make sure both my casual and dress shoes fit in such a way that taking my pants doesn't present a problem. This means no "skinny" jeans for me. Just bought two new pairs of "classic" fit cords. Haven't tried them, yet.
Also, I carry a few spare pads and briefs in my briefcase (perhaps that's what a "briefcase" was suppose to carry in the first place
I find that, often, I'm able to replace just a booster pad rather than the entire diaper. I'm lucky, in that I can sit, playing piano for three+ hours with no leaks. Sitting seems to apply pressure, stopping the flow. Problem comes, however, when I stand up at the end of a set. Most evenings, I head straight for the john.
The only other problem I've discovered is how to respond to customers asking, "How do you sit for so long without needing, y'know, a break?" My standard answer is, "Practice, lots of practice." Like I've said before, we all adapt to our own particular needs. Bo
