Same here. My wbc is always elevated though. What helped me alot is taking wheat out of my diet. I also started on a strong probiotic called VSL#3 at night and that has made the diarrhea go away. Like you I am still trying to figure out what to do and it has been an entire year of this rollercoaster ride. Last night we went to a church fair and I ate zeppoles and a hamburger with the bun. Today I am suffering for it!! I have found that for days like this antispasmodics help alot.
Hoping you will find what works for you soon.
