Thank you for the kind words...you're already on a good track regarding dealing with UC. Experience, unfortunately, is the best teacher.
Regarding tapering the rectal meds...by having enough refills and having the doctor leave that dosaging to YOU...you'll not have a tendency to wait to treat flares.
Some are able to get off meds, some (like me) are med lifers. I use the tapering method of the enemas to find a maintenance level. It's all paid off since my flares have never been as bad as the first one.
Let us know how the GI appt goes as well as the dietitian. Common sense is really a help regarding eating. While I don't believe food causes flares, the action of foods themselves in the digestive tract can sometimes create a huge disagreement and an exacerbation of some symptoms...such as gas and diarrhea.
I'm impressed with your doc that he put you on the oral/rectal 5ASAs....not all doctors agree that the rectal meds do any good...seems a no-brainer to me
One thing you should ask the doc is where exactly is your UC limited to...or is it throughout? and if he'll be doing blood tests for liver and kidneys since you're on the 5ASA meds.
Continue to feel better.
