I have been on this clinical study for almost 2 weeks and had mild nausea a few days ago but today was hell. Been very sick to my stomach all day! Even took anti nausea meds with no relief. I don't know if I have a stomach bug or bad reaction. Last infusion was 12 days ago. I have my second infusion this tuesday. Getting a little nervous now! Has anyone been on a study and had stomach upset this late into the infusion? I'm upset and depressed!
