I'm a month post-surgery now and have fortunately (knock wood) had no lingering pouch issues relating to the emergency gallbladder removal. The first 7 to 10 days weren't always great, mostly due to pouch-emptying difficulties, but once the abdominal pain was better and the antibiotics completely wore off things returned to normal.
Diet-wise, not much has changed. I ate gingerly the first few days but allowed my intake to normalize pretty quickly. This will be a very individual phenomenon, but my absorption was poor to begin with so I worked under the assumption it couldn't get much worse!
