Sorry for that very long post. As an 11 year survivor of stage IV disease, I experienced plenty of GI issues in the beginning. I concentrated on building upon the info gained from my clinical research career, asked professionals in the field of the GI tract lots of questions, read many websites, viewed countless webinars, took copious notes and documented the things I did that resulted in my GI tract working as good as it did before my illness. It took time and patience that paid off.
