It could be a type of neuropathy. I can only empty my bladder sitting down. And my by bladder normally has to be very full before I feel the sensation to empty it. Research autonomic neuropathy.

Just with regard to the bladder, I would love to be in your situation, Evan. I would love not to feel the constant urge to pee, and only to feel the urge when my bladder is very full. I have been involved with an "overactive bladder" forum for several years now and have noticed that there is no single certain remedy for this condition, unfortunately. People suffering from "overactive bladder" are having to try all sorts of different things.

Whatever works!😀
