I'd discourage anyone from taking more than two Lomotil at a time. The atropine can potentially cause serious heart problems in overdose. I do find that Lomotil works better for me than Imodium, but I use it in moderation - at bedtime and before an outing with inconvenient bathroom facilities (e.g. on a boat).
It can be very difficult to figure out why a pouch isn't working well. Sometimes it's within your control (e.g. kegels, fiber, antibiotics, Imodium, antispasmodics), and sometimes the pouch itself has structural problems. Pouchitis can be tricky, but it's usually pretty easy to treat. A course of Cipro or Flagyl is probably worth a shot for nearly anyone with pouch problems that just won't quit.
