I take Imodium at breakfast, dinner and bedtime.

the key for me is no eating after 6 pm, 7 the latest.

with my 6-7 hour cycle on Imodium, my last BM is typically at 1am and then I sleep the night.
i would lIke to snack at 9pm, but I find I like sleeping more.

If you’re going to snack at 9 PM then you might get the best results from something fatty, like peanut butter. That slows down the GI tract and might give you more time. I wouldn’t read too much into one bad night - that can happen to anyone, with or without a J-pouch.

I generally sleep through the night, 7-7.5 hours, but sometimes I have to get up earlier to poop, and then go back to sleep.

I rarely get a full nights sleep.  Last night I went to sleep at 10:30PM then woke up at 12AM to go , then 6, 6:30, 7AM.   I did snack quiet a bit and had an alcoholic drink.  I get up at least once and have a hard time getting back to sleep.  I know it affects me but taking sleeping pills is not a very good option either I found out.  Just keep trying I guess.

For me it depends on how much I eat and if I eat late. If I behave myself and don't overdo the eating or do late-night snacking, I usually get up once during the night, sometimes twice.
