I realized I've never given you the official title of the trial:
A randomized Double-Blind Placebo Controlled Trial of Neratinib After Trastuzumab in Women with Early Stage HER-2 Over expressed Amplified Breast Cancer
The nausea went away, so I think maybe it was a bug. So far I have no side effects from the trial drug. I have a mammogram later this week. So far so good!
