I've had the seasick feeling in ED.
It can be controlled a bit in the ship if you keep your head pointing towards your direction of travel when turning and don't try looking around to much unless traveling straight.
The SRV I found too much to handle, only way to solve that was to drive quite slowly.
The problem is exactly the same a seasickness really. It is simply that your body is not doing what your eyes tell you it is doing.
On a boat, the problem can be solved by looking to the horizon, then you can gauge how much you are really moving. Obviously this might be being on deck in some blooming horrid weather.
But in VR we don't really have that option. Your body is not moving even if your eyes tell you different.
I found that the roll and pull back to manoeuvre was preferable to using yaw for side to side.
Also keep rate of tune down.
Close you eyes while in H-Jump if it's a long one as after a bit the graphics start to twist left and right.
Just my thoughts so far.
