I can' tell what quantity of leakage you're dealing with, but two things that I do are 1) I don't let pouchitis go untreated. Nighttime leakage is often a first sign of pouchitis, and 2) I take Lomotil at bedtime, but not during the day. 

Others have found a small fatty meal (e.g. a spoonful of peanut butter) helpful at bedtime.  Good luck.

Well, for me it is managable with a sanitary pad when I'm healthy.

I've found out that Immodium (two pills, 4mg in total) reduces the amout of leakage but that there is still some.

I just wanted to see how others deal with it as nightly leakage obviously is a well known problem when having a J-Pouch. I was looking for some other tips than the ones I already know  

When dealing with something like that I guess everybody tries to find the best solution and with some input from others and some procedures that worked for them one might come closer to this 'best solution'

For example, I haven't heard of that tip with peanut butter yet. This is the kind of input I hope to see in this thread

Levsin at bedtime, Depends disposible underwear, if pouchitis related treat the pouchitis as well.
