Does anyone have any suggestions for easing the cramps and diarrhea? I have been on imatinib 400 mg for the past 9 months. My numbers are good. After wading through a rash and mouth ulcers, things were settling down until two days ago. Then I began to feel fatigued, have stomach cramps and diarrhea. Many of you say you cycle through these kinds of episodes periodically. Just wondering how you cope with them.
