Has your doctor done a pouchoscopy with biopsies or a defacting pouchogram? The other tests they sometimes do are small bowel series to look for inflammation in other portions of the small intestine that could also be causing your symptoms.
I have chronic pouchitis and need antibiotics all the time. When I am not on them, even for a day, I experience symptoms somewhat similar to what you are describing and rapidly. I describe mine as lots of gurgling with a constant uneasy feeling in my intestine with nausea sometimes, coupled with increased frequency to the point of annoyance, looser stools, abdominal pain and general malaise. I also have worsening symtpoms when stressed or very overtired (which seems to be always since getting a jpouch and interrupted sleep every night).
If your inflammation is not severe enough to warrant antibiotics, I guess the best thing you can do is get extra rest, drink lots of water and avoid sugars and pasta, whites/flour as they do aggravate many people's pouches, mine included.
Good luck and hope you feel better soon.
PS. I think what may happen to many of us once we take antibiotics for pouchitis is that they improve pouch function dramatically so that when no longer on them, even if pouchitis is quenched, you feel as though something is wrong with your pouch (when in fact there may not be. I believe this is due to to the impact antibiotics have on greatly improving pouch function.
