Mine‘s getting so accustomed to cold showers that I a) absolutely do not mind cold water for swimming etc. anymore and b) could not enjoy warm or hot showers anymore. They just weren’t nice at all.
Hard to say really but certainly greater than 12 hours, maybe even 18, after having the urge to pee. I tend to forget about it and rarely wake up during the night to go.
Huh. I was diagnosed and in my 30s, and I pissed myself shortly after starting my meds. There was almost no warning, just zero to a hundred within the course of a minute. Hasn't happened since, just a heads up.
