Ignore me if this is completely not useful for you ... I was constantly going to the loo, drove me mad, meant I couldn't get a night's sleep, and during the day this intense and irritating half-need, all the time, it was like I never actually finished weeing, there was always a little bit more, and my bladder had to be completely empty no matter what. I even remember posting on here because (I think as I recall) cat flaps were like sandpaper and hubs was kind of getting 'burned' whenever we had relations. It wasn't an infection. I was on HRT back then. In desperation, and due to other issues, I saw a herbalist. She said it was my adrenalin function, part of fight or flight, because that's what animals do, feel the need to empty their bladder. She gave me some herbal medicine and within a couple of weeks (after months of come and go discomfort) it had gone, including all the dry as dust stuff. I carried on seeing her for a couple of years.
Anyway, these days, whenever I get a sniff of that fight or flight looping one of the things I do is drink Twinings Sleep (valerian and orange blossom) x 2 before bed for a week or so. However, valerian is a pretty strong herb, maybe even in a Twinings thing from the supermarket, I don't know. I'm not suggesting you take it, just saying what I found useful.
