I don't have any symptoms at all. Sure, I'll get a loose poop or two if I eat too many beans, fruit, etc, but that was my pre-UC normal. To me, it honestly sounds like you are still mildly flaring. You may want to discuss (with your doctor) upping your Asacol to 12 (or switching to a different mesalamine drug, since you're seeing some in your poop) and upping the enemas to nightly until the symptoms are completely gone, and have been gone for a couple of weeks.
Status: Remission since May 2009!
