I haven't used Metamucil to deal with nightly incontinence yet but I have tried Loperamide and found out that it reduces nightly incontinence for me. Sometimes I have none, sometimes only a reduced amount but most of the time it helps to a certain extent.

Metamucil is helping me when everything feels quite 'restless' in my belly and so on. Then I take one and it's getting calmer.

But you can try it. If it helps you'll notice it and if not you haven't done any damage to your body either.

Only thing that has helped me deal with not turning my bed Into a poop puddle, is to take a few Imodium right before I go to sleep.  

Chris, I take psyllium fiber (half Metamucil) at dinner time. The effect of that (IMO) continues through the night. I don't choose to add bulk (like Metamucil) at bedtime, but even that is worth a try to see how it works for you. I do take Lomotil at bedtime.

Are you sure you don't have pouchitis? Nighttime incontinence is often the first symptom.

Thank you for the info, Scott.   I am currently being treated for pouchitis because the incontinence has gotten worse recently, but even after a round of antibiotics, I still have 1-2 episodes of nighttime incontinence.  I'm fine during the day.  I do take 2 -4 Immodium before bedtime and I also take VSL#3 twice a day.  Since my surgery over a year ago, I've only had a handful of "dry" nights.  I'm getting ready to go to Cancun in December and I would really like to get this all figured out before then.    I don't eat or drink anything after 6:00 p.m.  I feel like I've been trying everything in the book with no real success.  You always have encouraging words and I really really appreciate that.     

I find Lomotil works better for me than Imodium, so an Rx for that might be worth a try. Some folks get great results from a small, fatty "meal" at bedtime (like a spoonful of peanut butter). If you take a sleeping aid I'd suggest stopping. A month or two of aggressive daily kegels might increase your resting sphincter tone a bit. Finally, perhaps the antibiotic you used didn't do the trick, and a different one might work better. So you have a few things that may be worth trying. Good luck!

Thank you, Scott.  I cannot thank you enough for your great suggestions.   You have an impressive amount of knowledge that all of us benefit from.  Thank you!
