I've made it over a year no potty but I still can hold my bladder. I never wet the bed. During the day it flows when I'm relaxed sometimes I have to stand up when I feel the pain to go. Messing I can hold it at times but have had accidents before.
Only if someone says anything I'll just say I need diapers due lack of control and the bagpack is aways with me. No sense to tell them it's like saying "opps I farted, I have gas" but if really bad and I can smell it I'll say my bad I'm having gases.
I did the same towels, undies, rags whatever I could get my hands on. One time I showed my mother my makeshift diaper. She was starled by it.
Of course grocery and trash bags
