Hey jbug,
Rice, pasta, bananas, white bread. Potatoes can be done. Make them plain ~ no butter, sauces or herbs. Other than that, stay away from the fruits and veggies for today ~ they're quicker and easier to digest than the starches, which adds to the outflow.
Oh yeah ~ I stay away from Immodium. You may have a tummy bug, which means the stool has to come out one way or another. My ER doc advised me to
never do the Immodium, because that brought on relentless vomiting.
