I haven't been on this site since my last post of mine that you commented on; I am about 4 weeks since my J pouch construction; sounds like I am having similar symptons. Lot of nausea and my bag is filling up with complete liquid several times a day; I made a trip to the ER last Friday (Sept 5th) and received two bags of IV fluid for dehydration...thought I was drinking enough, however, it appears once you can't keep up with the bag output, it's already to late. Trying to re-adjust to things now, added over the counter Imodium A-d (Mint Flavor) once or twice a day. Added steamed rice yesterday and that really thickened things up...looking to establish that balance of consistency so I don't get dehydrated again. Other than that, basically dealing with tolerable off/on rectal pain right now.
