Have you been eating a variety of foods or just the "safe" foods? Because a lot of foods I would think would make everything watery actually thicken me up, so I think a lot of it depends on your body. Bread and pasta don't always do much for me. Watermelon and pizza do.

There is also prescription strength Imodium. I would call your doctor soon!

Have you tried Metamucil yet? If you can stand the grainy texture of it, it might make a difference.

try benefiber. Make sure you are taking the immodium 30minutes BEFORE you eat. most docs will tell you you can take 8 a day total.
add nexium (prescription neeeded from you doc)
also you can get a prescription for tincture of opium
other foods that have helped me in addition to what you said - potatoes, rice, oatmeal, peanut butter - the real kind- not the sugar filled stuff in packages). So my magic.. gunk it up breakfast is real oatmeal with some benefiber sprinkled on it and peanut butter toast.

Don't drink too much water.. try pedialyte, a true WHO solution from Jianas brothers, or ceralylte... all day sipping it. Use this as your only beverage.. rather than plain water. My doc has me on 2.5-3 liters of it a day.
Do not drink while eating.
and do not drink hot liquids or eat hot liquidy things like soups.
Look up an "anti-dumping" diet. Its usually prescribed for people after gastric bypass surgery. But my doc did all of the above and had me use that diet when I was in your sitatuion. It worked.
good luck

Are you using the same protocol now that you have the end ileostomy or just when you had the loop?

Don't drink when you eat.
Don't drink all at once sip through out the day.
Eat salty snacks.
Try metemucile cookies.
buy some vitalyte it really helps.
You really need ceralyte or the WHO oral rehydration solution. If you get cerlyte get the plain. This is a must if you are dehydrated.

This is the difficult part of all of this. Once reconnected, things improve greatly. Meanwhile, trial and error! I used Vitalyte as a hydration liquid and it worked for me. You can get it at camping stores or online.
