Same here. I started weting my bed again in my late 40's and then not long after I started having some day time incontinence. Gradually it got worse and now I am dependant on nappies 24/7.
I got diagnosed with overactive bladder. Tried a bunch of meds. None worked or if they worked the side effects were unbearable. "OAB" is a BS umbrella term for "your bladder isn't working right". At first I was satisfied with having something to call it. But after a while I wanted to know what caused the OAB and what can cure it. Apparently it's idiopathic and seemingly incurable.
