Discovered this recently with a couple of mates 55+ who barely drank anything if they knew we had a day out 'doing things' (we were on holiday together, curt-break style). One up super-early to have a tea, so have a wee before going out for the day.
Both said they hydrated at night and expected to have to get up at least once overnight to wee, while on holiday, so not all the time.
I can see their thinking!
I have a three hour concert coming up in early Dec, evening (in a cathedral, so not ' modern amenity central' 😂. I'd generally expect to wee once in that time, esp if I'd had 2 wines, say, over the previous 2 hours.
Does anyone else deliberately dehydrate?
