I generally take one Lomotil at bedtime only. I've been lucky enough to never get clogged up, but I always drink plenty of water. I think a J-pouches intentionally reducing fluid intake is making an error.
For years I pooped whenever I had to pee. Eventually I decided I was better off just peeing many of those times, so I worked pretty hard to get the hang of it. I think it's better overall. In particular, drinking plenty of water no longer fools me into thinking I have to poop more often.
