MOTION SICKNESS: If you are prone to motion sickness, try this tip. Look straight forward and do not move your neck/head. Only «look» around by moving your eyes. If you still get sick, only look straight forward. Generally, motion sickness can be overcome by continued use. The moment you start to feel sick, stop viewing, but keep coming back to the VR and most likely you can get over getting sick.
