My experience is analogous to yours. Initial motion sickness, *strong* de-realization and de-personalization (especially with hands, but also my torso and legs).
Nausea didn't get better and seemed to be present when my head was turning but the camera was moving either the opposite way or in the same direction but too fast.
I have some really good memories of spending hours inside of Obduction VR (highly recommended if you liked Myst / Riven / The Witness / etc), but the de-realization was so severe that I ended up abandoning that form of entertainment out of concern for my sanity.
